Throttle parts - Motorized by servos

[freddehboy]

Hi

I am almost finished to sort out what I need in electronic and other stuff, see bellow:

1
I need a main board which buttons, switches and sliders ect. etc.:
http://www.phidgets.com/products.php?product_id=1018

2
I am think that a cold unit is far better than warm so the throttle and spoiler willl be controlled by servos:
http://www.phidgets.com/products.php?product_id=3200

a
Is there a better concept than servos if you are considering the temperature and the noise from the unit?

b
How about DC Motors if you compare with servo?

c
I have seen that the servo has a potentiometer ?


3
I have understood that the servos must be controlled by a card:
http://www.phidgets.com/products.php?product_id=1061

4
I am needing something to feel where the ex. throttle is, like a slider:
http://www.phidgets.com/products.php?product_id=1112

handle / Switches and Buttons at:
http://www.simparts.de

There is not so much to say more than that I need some of these type too :)

I have seen: http://www.simparts.de/epages/15465782.sf/de_DE/?ObjectPath=/Shops/15465782/Products/737-TH-001

Is the above a kit of these products:

http://www.simparts.de/epages/15465782.sf/de_DE/?ObjectPath=/Shops/15465782/Products/737-TH-0002

http://www.simparts.de/epages/15465782.sf/de_DE/?ObjectPath=/Shops/15465782/Products/737-TH-0004

http://www.simparts.de/epages/15465782.sf/de_DE/?ObjectPath=/Shops/15465782/Products/737-TH-0005

http://www.simparts.de/epages/15465782.sf/de_DE/?ObjectPath=/Shops/15465782/Products/737-TH-0006

http://www.simparts.de/epages/15465782.sf/de_DE/?ObjectPath=/Shops/15465782/Products/737-TH-0007

Is these stuff of good quality?

I like you to comments these parts and tell if I have fogot something important!?

Hi, have you thought about Arduino as a controller/interface for the motors OR servos? it is MUCH cheaper requires a little bit of C++ knowledge but I can help you there (think about ARCOM_by_Marc customized version) http://x737cockpit.wordpress.com/arcom_by_mac/

Hi

I take the hardware who is supporting my pmdg737ngx so I am not against other than phidget!

Best Fredrik

[fordgt40]

The difference between servos and dc motors is

Servos have their own positioning info via an internal pot whereas a dc motor needs a separate pot. However, if you want manual overide with a servo then you also need an external pot and most importantly a servo controller card that can be switched off via software so that you can move the servo by hand. If you cannot switch off the servo then it will always resist any manual force

You cannot easily control the speed of the throttle levers with servos other than by gearing or software delays, if yourcontrol card supports this. Also, servos mostly move circa 180 degrees only and the throttle arc is circa 80deg, so some gearing is inevitable. With servos there is a danger that the geared movement with be "notchy" and not smooth.

Dc motors with control cards are easier to gear and control the speed with the right control cards and sotware, however, for manual intervention you will need a "slip" clutch to disengage the drive and two pots.

In my view dc motors give the most realistic performance, but have greater technical demands.

"I take the hardware who is supporting my pmdg737ngx so I am not against other than phidget!"

Currently, no hardware can fully access PMDGX internal controls/outputs, other than some people on this forum who have been able to write sections of code to link their MCP and FMC`s etc. Opencockpits are trying to develop a software interface for their cards/sioc programme - try searching this forum.

If your hardware choice is going to be based on being able to support PMDGX, then I fear you may have a while to wait:(

[mrmaster]

I agree on the part about the DC motors, I saw many videos on youtube and as I am also planning to build one my own, I settled on using DC motors.

If you use Prosim737 it would be very easy to control the Arduino.

All the best,
Marc

The products for servo controlled throttle;
http://www.phidgets.com/products.php?product_id=3200
http://www.phidgets.com/products.php?product_id=1061

Question:
1
Can the above servo be connected to another servo card?

2
Can I use the servo with ex. Opencockpits servo card? I think was the answered is! :)

3
Do you mean that the movement won´t be smooth of the throttle and I need to tell the speed to the servo through my software?




Dc motors with control cards are easier to gear and control the speed with the right control cards and sotware, however, for manual you will need a "slip" clutch to disengage the drive and two pots.

4
I am not against DC motors but just the noice and temp of the motor but what about it?

5
”slip" clutch to disengage the drive and two pots.” What is a ”cluth” look like?

6
Way 2 pot? I now what pot is but way two?




In my view dc motors give the most realistic performance, but have greater technical demands.

7
Is the demand so much bigger than with servos and will it be so much better than servo controll?

Is opencockpit a good developer?

Piople, who build cockpit, what are the useing in:
Hardware developer
FSX Aircraft
Projekt magenta or prosim737

Best Fredrik

[verticallimit]

I use DC motors for my throttle.
It workes fine for me in 2 years now.
I use a very simple interfacing, i use relays for controling the motors.

LINK (http://www.mycockpit.org/forums/downloads.php?do=file&id=434) see page 8

The throttel lever have the original slip clutch between the motor and the handle.

I use Open cockpit and have no problems.

Hi

Based on your questions, you need to read and research more on this subject. You will not succeed on a simple question and answer session - you need to understand this subject better.

I am not going to research your suggested hardware in detail, that is your job, however, the phidgets references seem ok. But, you also need to check out how they are programmed and are there inbuilt software routines to access FSUIPC offsets

Opencockpits cards are fine, though I do not think that there is a native speed control for the servo. However, this can be emulated in software.

With servos there is a risk that the gearing and movement may be "jerky". DC motors with proper gearing are not so at risk. There is no definitive answer to your question

DC motor noise is subjective and depends on the view of the person listening

A clutch operates the same way as in a manual car - it disengages the drive from the motor. Do a google search on polyclutch

Sorry, I misled you about 2 pots - in either dc motor or servo option will will need one external pot

Item 7, I had a symulatory throttle using servos and have now replaced them with dc motors. DC motors option is considerably more expensive - do the research

David

[freddehboy]

Hi

I will go for the dc motor but before I must get a answered about the pmdg737ngx in what hardware I can use :)

I have mail to all developer and ask it!

If you choose phidget or some other developer there you need to program to interface the hardware with fsx. The simple question is, must I by mesel program a code for the hardware to work in fsx and mine specific aircraft?

In that case its all depends on me if there will work or not. I can manage C++ because I have program in it for some years ago :)

Best Fredrik

[Philb737]

Fredrik,
Check your PM!

[mrmaster]

If you want further advice, could you tell us if you would use Prosim737?

Marc

[freddehboy]

I do not know yet? Its deppends if prosim737 works together with pmdg737ngx or not!

Hi

Someone here talk about a joystick card like: http://www.leobodnar.com/products/BU0836A/

This card is the way to go for my but how can I interact a servo controller card .....?

To work with the Bodnar card i must go through it and connect all the things to it like all the throttle part!?

This sound really great and I shuld have the card as i master card ocr like that!

A joystick card is undeppendent of what aircraft I have so is shuld work with my aircraft!?

Best Fredrik

[mrmaster]

the bu0836x is a input joystick controller with some problems with rotary encoders. If you want to use buttons, that is the best way to go, but beware, you won't be able to control any hardware with this card. (Maybe some LEDs but that is a bit complicated)

Does anyone know if PMDG 737 NGX works with PROSIM737? if yes, I think you should use ARCOM and Arduino.

Marc

[freddehboy]

Hi

It semans that prosim737 did not need underlying aricraft as I thought and the software does not work with VrInsigth untits, in that case I cannot use it. The units I have are almost new and I have not afford to change it so I have to go with pmdg737ngx!

That is the reason that all the stuff must work next to pmdg737ngx!

Best Fredrik

[mrmaster]

if the pmdg 737ngx works with FSUIPC you would be able to drive the throttle with Arduino

[freddehboy]

See: http://www.scribd.com/doc/76829977/7/FSUIPC-users

That sounds to work? :)

Do you mean the throttle will works with A/T by AP too//
Best Fredrik

[mrmaster]

I just looked through it but if you are able to access the a/t value (the input from the ap to control the throttle) it will be possible to send this value out too the Arduino and process it there. (With C++ you can write to the Serial Port and thus control the Arduino)

Take a look into the C++ SDK for FSUIPC and the Serial library for C++ you should be able to do it.

Marc

[fordgt40]

I should check out all I/O cards to see which suits your pocket, flexibility and most importantly ease of programming/access to FSUIPC - they are not all equal:)

Other cards include

Opencockpits
Pokeys
Phidgets
FDS SYS
Sismo

To name but a few

David

[freddehboy]

Hi

Can someone confirm that pmdg737ngx is working together with fsuipc?

One thing is what pmdg say and write, another is if it actually work! :)?

Edit; See: http://forum.avsim.net/topic/352127-pmdg-737ngx-sp1-available/

You can see that one of the changes are: "Added numerous LVARs for cockpit hardware users to access via FSUIPC or the freeware LINDA utility."

It must mean that my dream can come true :cool: :)

The last thing if PMDG 737ngx is working with project Magenta or prosim737?

It is so much better to have the OB and IB dispaly on physical display and not too see the display on a screen :)

Best Fredrik

[freddehboy]

Hi

I will be able to use fsuipc for my axes and buttons assagment, see: http://forum.avsim.net/topic/351903-can-i-use-pmdg-737ngx-with-fsuipc-calibrated-controls/ :) :)

For the physical screens (Outbound, Inbound and Engine) I will use the 2D frame of the display!

Ex: You click at the Outbound display in the Vcockpit and get up the 2D diskplay of the VC display. I will use this 2D frame for the physical screens for my owm MIP!

Do you understand?

Best Fredrik

[freddehboy]

Hi

I have decided to use the joystick cards from FDS "FDS-FC1" for trottle and my Yoke!

Since my aircraft is supported by fsuipc a need some hardware for servo or DC motor who can be programmed in fsuipc?

I know the diff... between servo and DC motor. DC motor is better than servo but how is it with the heat?

I like servo as they are simple to install and has good temp!

Phidgets has a great range of proucts but can the be interact with fsuipc?

If that is the case I have to alternative:

http://www.phidgets.com/products.php?product_id=1061

A good DC motor choice!?

Instead to buy prosim737 or something else I, for the physical screens (Outbound, Inbound and Engine), will use the 2D frame of the display!

Ex: You click at the Outbound display in the Vcockpit and get up the 2D diskplay of the VC display. I will use this 2D frame for the physical screens for my owm MIP!

[freddehboy]

Hi

Bellow is the answer I got from PMDG about to simulate the A/T:
"The SDK doesn't provide any throttle position data. However the NGX
autothrottle drives the standard FSX throttles. He can pull the throttle
position from the FSX and send it over to his physical servos.
He will need to introduce some damping into the throttle motion if he will
be doing this. The NGX AT controls the FSX throttle pretty fast, and the VC
thrust levers use a code like this to smooth their movement:
NewPosition = 0.95 * PreviousPosition + 0.05*FSXThrottlePosition
This code runs each NGX refresh cycle (18 times a second) and smoothly
drives the VC levers towards the actual FSX throttle position."

Best Fredrik

[freddehboy]

Hi

I have seen that I can use phidgets since it is supporting fsuipc like my aircraft so there is no probblem to use it together.

I have found the DC motor:
http://www.phidgets.com/products.php?category=24&product_id=3257_0

Controll card:
http://www.phidgets.com/products.php?product_id=1065

Is this a good choice, if I can use it for fsuipc?

Best Fredrik

[fordgt40]

Are you sure that this motor has enough torque to move the levers and overcome friction. I needed circa 7.5 kg/cm torque when converting my Symulatory throttle. Also, if you want realism then the throttles take around 5 secs to move from idle to "firewall". You need to calculate your gearing accordingly to keep the necessary torque within the motors speed range

I should also check that Phidgets have easily accessible user coding for you to write the necessary programme to control the motor speed (as per the PMDG example) and access FSUIPC offsets.

David

[freddehboy]

Hi

No, I took this motor as an example :oops: Bad one :)

Do you mean that I should calculate the speed according to the range the throttle will travel and that will result it the correct torque!?
I think I understand correctly, in some way? :)

Best Fredrik

[fordgt40]

Torque is basically the force that the motor can provide, it will vary with speed and voltage
The steps you need to complete are

Establish the likely torque needed to move your throttle levers from either idle or max. You can do this by using a spring balance to pull on the end of the lever at 90 deg to its pivot point. Take a note of the value and then multiply it by the distance from the pivot point to where you applied the spring balance. This will give you the force ie "pull x distance".

Then look for a motor that has that torque and draws no more current than the controller card can provide. The motor needs gearing to get the speed down to circa 15 revs a minute, this will also give you more torque. Then calculate the throttle arc of movement, probably 75 deg. Given that you want the throttles to cover that 75 deg of arc in around 5 secs then from that you can calculate the necessary gearing between the motor pulley and the pulley on your throttle lever. Remember you can always slow down the motor by using the controller card

For example. If the throttle movement arc was 60 deg, then that is 1/6th of a circle. If your preferred motor has a speed of say 20 rpm, then it will move the levers across their full full range in 20rpm divided by 60 secs = 3 secs per revolution which equals 3 secs divded by 1/6th which equals 0.5 secs to move the throttle levers across their full range. Clearly, this is too quick, so you will need gearing between the motor pulley and throttle lever pulley of a ration of 10:1 to get the correct speed

David

Hi

I am trying to follow your example but have you calculate correctly?

I got 20 / 60 = 0,333 sec 0,3333 / (1/6) = 2 sec?

Anyway it should take 5 sec for the lever to travel the whole range!

If I increase the rpm I get less time in sec and that cannot be correct! :|

Best Fredrik

[fordgt40]

Yes

Look at the logic and what I said.

If the motor rotates at 20 rpm then that is 3 secs per revolution - 20 revs x 3 secs = 1 minute

If your throttle arc is 1/6th of a revolution then the levers will move across their full travel in 1/6th of 3 secs which is 0.5 secs

David

[freddehboy]

Hi

I am trying to use the same calculation for 15rpm:

60 / 15 is about 4 sec, the range 1/6 of 4 ~6 sec

I am understand the logical but is unsoure at the result since someone here said 15rpm = 5 sec but it could been about 15rpm!? :)

Best Fredrik

[fordgt40]

I did not say that 15rpm equals 5 secs!!!

I said that you need a motor of around 15 rpm and that you need to complete the throttle movement across its range in 5 secs. From these parameters you can calculate the gearing between the motor and throttle lever pulleys.

David

[freddehboy]

Hi

Ok, sorry missunderstood at that point so now I will calculate the gearing!

Best Fredrik

[freddehboy]

Hi

If are comparing a real throttle are the:
Start pos... good at 40deg...
End pos... good at 100deg...

Best Fredrik

[freddehboy]

Hi

I have look at phidgets dc motor and I have not find so many but this maybe can be a good choice?
http://www.phidgets.com/products.php?category=24&product_id=3268_0
http://www.phidgets.com/products.php?category=24&product_id=3268E_0

I have look at the gearing and understood its logical structure etc. etc ! :)

Best Fredrik

[fordgt40]

The first link looks ok as you do not need the extra cost of an encoder as in the second link
How are you going to achieve manual overide?
Glad you now understand the "gearing" :)

David

[freddehboy]

Hi

As for controller:
http://www.phidgets.com/products.php?category=12&product_id=1065_0
http://www.phidgets.com/products.php?product_id=1064

It seams that the controller 11065_0 can controll the direction of the motor?

For manual overide I have think this joystick card can match: http://www.flightdecksolutions.com/pcupload/FDS-FC1-V1.pdf ?

I thinking for the pot...: http://www.simparts.de/epages/15465782.sf/de_DE/?ObjectPath=/Shops/15465782/Products/700-4000

Best Fredrik

[fordgt40]

I think that you need to slow down a little and stop picking components :)

Have you checked how to programme phidgets, can it easily access fsuipc offsets?
Have you checked other h/w such as Opencockpits and sioc control language?
Does your preferred motor control programme have all the commands that you will need?
When I asked about manual overide I meant a slip clutch. With a geared motor it is highly unlikely that you will be able to move the levers by hand

Have you designed the layout of the throttle, its gearing (direct gears or belt and pulleys etc) and how to install the pots - coupled by direct drive gears or other

This could be very expensive if you select components at this stage :)

Not trying to dampen your enthusiasm, but trying to help you have a disciplined approach to what is a quite complex project

David

[freddehboy]

Hi

I begin this way because I need to know the cost of the project but maybe there are the wrong way to start?

The thought was to know what I need if phidgets is not the way to go :)

Phidgets sites has a good product range to look for the correct components so that is way I beging in this way?

I have not found a developer where you do not have to program//

I have checked other developer, it seams that none else have that wide range of products like phidgets has?

If there is a developer who are given sutch program: "Does your preferred motor control programme have all the commands that you will need?"

I will take it if it works with fsuipc?

FSUIPC is a overalls condition//

Hi

[fordgt40]

What do you think FSUIPC does?

Have you looked at the range of Opencockpits control cards and their SIOC language which provides extensive I/O control?

David

[freddehboy]

Hi

I have shall look more closely in opencockpit product range :)

I have seen: http://www.throttletek.com/

The price is very reasonable in that case I can buy it and let them modefied the unit and start to build my yoke instead, I have plan to build my own overhead panel too, maybe :)

To build a throttle motorized cost about 4500:- in Sweden. Buy this unit about 4300:-!

Best Fredrik

[freddehboy]

Hi

I have checked openccockpit and theirs software looks better than i thought :) If it works good with fsuipc or if I can alternatively make some lua or like that!

Can a steel buy dc motor from phidgets too fit together vid opencockpit´s (OC) I/O card since OC have noy any dc motors´?

Do you mean that "slip clutch" is like a on/off for the drive axe, do you mean I can choose that dc if I am want to manula overide the engine?

I think FSUIPC is just a program to program the controller with offset as the fsx can read to do stuff for the simulator!?

Best Fredrik

[fordgt40]

SIOC works perfectly with FSUIPC

You can use any motor with OC cards, provided that it meets the control cards parameters

You must use a slip clutch if you want to manually override the levers if driven by a geared dc motor- as suggested before do a google search on polyclutch

FSUIPC is basically a "door" into important variables enabling you to read/manipulate many FS9/X internal variables. It also can read control axes, set up control sensitivity, assign button presses, generate mouse macros, link to other pc`s across a network and much more. It does not programme a motor controller

David

[freddehboy]

Hi

Now have I finally two good alternative in what DC motor I should choose :):
http://shop.paolettiferrero.it/product.php~idx~~~3306~~RH158+SERIES~.html

My condition are:
The USB DcMotors board can manage Dc motors from 5V to 36V, up to 1Amp (included maximum peak of 2 Amps),

The two DC motor which match have this data:
1 - 12VDC; 580mA; 1Nm = 10.19716 kg-cm; 200:1
2 - 12VDC; 300mA; 1Nm = 10.19716 kg-cm; 500:1

These two clutch will match the 6mm axe:

3 - http://www.polyclutch.com/mechanical-slip-clutches/series-16-slippers
4 - http://www.polyclutch.com/pneumatic-slip-clutches/slip-aire

I like the dc who has more mA, do you agree, what about 500:1?

What Polyclutch should I buy, I think the less expensive one!?

Edit: I have seen that the polyclutch is rather expensive, about 420pound, is not it?
Does i need a polyclutch to servos, if not what will it be?

Best Fredrik

[fordgt40]

I would go for the lower rpm and lower ma.
Sorry, I have no experience of Polyclutch, though a number of other builders have used them. I made my own clutch using a lathe and milling machine - not for the faint hearted!
You cannot manually override a servo if it is still under "control" . Although you can switch off a servo under programme command with some control boards eg Opencockpitsdo and then move it by hand. If you wish to manually override the servo at any time then you will need a clutch and some good programming :)

David

[freddehboy]

Hi

First I am very grateful for your big help :)

I should maybe go for servos for its simplicity to build and install in the throttle?

I can maybe in the future upgrade it?

The whole reason for a motorized is for the realism and to have servos in one way is far better than nothing so back to a servo solution :)

"You cannot manually override a servo if it is still under "control" . Although you can switch off a servo under programme command with some control boards eg Opencockpitsdo and then move it by hand. If you wish to manually override the servo at any time then you will need a clutch and some good programming"

Do you think I can swith the sevo OFF with the same button as A/T disconnection or like that and simply swith the servo ON when the A/T is engage!

Anyway I have choose this board: http://www.opencockpits.com/catalog/servo-motors-card-p-42.html?cPath=21_32
You mean this board has a such function or like that?

I have choose this servo for throttle:
http://www.hitecrcd.com/products/analog/boat/hs-815bb.html

This for Speedbbrake;
http://www.hitecrcd.com/products/analog/standard-sport/hs-422.html

But will this servos work with the usb servo board?

I maybe will build a clutch in the future but it is to much to buy?

I will send a question to OC and ask about this. I will be back when I have the answer//

Best Fredrik

[fordgt40]

I can maybe in the future upgrade it? - unlikely, the mechanics are different

Do you think I can swith the sevo OFF with the same button as A/T disconnection or like that and simply swith the servo ON when the A/T is engage! -- yes with SIOC

Anyway I have choose this board: http://www.opencockpits.com/catalog/...ml?cPath=21_32
You mean this board has a such function or like that? --- if you send a value of 0 to the servo, it turns it off. To do what you want you will also need to buy Opencockpits USB expansion card and a mastercard

I would use the same servos for both the throttles and speed brake

Remember that you will need to use gearing between the servo and the throttle levers to get the right speed, assuming that the servo drives the throttle levers to quickly or use some clever programming in SIOC to introduce delays. Either way, you run the risk of jerky movement as explained earlier in this thread

I use miniature Hitec servos in gauges running on the OC USBservo board - you need to change the servo wiring harness

David

[freddehboy]

To do what you want you will also need to buy Opencockpits USB expansion card and a mastercard

Is the reason that the USB Servo card does not handle such function I am look for?

All of this sounds like a DC motor solution is better and sounds easier to setup! :)

Stupid question, anyway, can I use any manufacturer of Clutches by my choice? :)

I will investigate botch the alternative// Best Fredrik

Instead of asking questions you should read the manuals and understand what the cards do and how. Also, as advised earlier, you need to do much more research before making decisions.

Answers to your questions above can be found in Opencockpit`s documentation.

Hi

Its correct, my thought are faster than my hands :)

I would go for the lower rpm and lower ma.
Sorry, I have no experience of Polyclutch, though a number of other builders have used them. I made my own clutch using a lathe and milling machine - not for the faint hearted!
You cannot manually override a servo if it is still under "control" . Although you can switch off a servo under programme command with some control boards eg Opencockpitsdo and then move it by hand. If you wish to manually override the servo at any time then you will need a clutch and some good programming :)

Hi David,
Can you show us how you made your Diy clutch?

Hi David

I have found this: http://www.aerosimsolutions.com.au/throttle.html maybe a solution?

I can also built the throttle so I am able to upgrade it later to be motorized, a good thought :)

I think it´s more fun to have a really throttle, motorized or not, than none at all!

Hi

I have decided to wait with motorizion of the trottle I will build so I can upgarde it later :)

Bellow are the parts that I have choosen:

These are the main parts but are there another thing that I have missed?

I have a plan and a description in the way I shall build my throttle and maybe I motorized it along the road but not at the moment.

Hi

I have decided to wait with the throttle build since in this project is included a overheadpanel, forward and AFT but just the things like PMDG737ngx´s has :)

I will start with that and see about the throttle later//
Best Fredrik

[freddehboy]

Hi

I have been thinking alot and concluded that the the most reasonable is to start with the throttle part
of my project as I talk about from the start :)

I have change the product list to be more cheaper and with DC solutions :)

Product are as bellow:

Pot 10K
http://www.opencockpits.com/catalog/pot-10k-p-123.html

1
Are there another motor controller card but also handle digital input like the leobodnar card?

2
Is a rotary pot better than slide pot to the throttle?
The HiFi Slide pot 10 k is expensive one so if the answered is no can I choose whatever slide port I like to buy?

3
I may use a pot to the reverse handle (last product) but is that a good solution for the rev...?

Glad if you comment my product choice//
Best Fredrik
