Electric Motors for Motion Base?

[wannabeaflyer]

Just to say thanks again Marnix guessed there was not gonna be a lot of change left over with the spec of gear you listed LOL oh for a few pounds more pocket money as with the rest of the crew will keep a close eye on your project as and when you post updates great stuff .. What are you gonna do regarding controll software ??

I have 5 wheelchair motors at home, but I need speed controller so I can use for motion platform.
My biggest problem is what controller to buy and where. any ideas?

Hi Goose personally im using the KT5198 as recommended by Jim, this board has so far proved to be Graet value Bang for bucks wise and am presently still coding the software using VB6 & Simconnect ( found it a little easier to use than Visual C# ) all of my efforts really have only been possible because of the work Jim has done and released , but getting back to controllers there are now a raft of realativly cost effective controllers out there for guys like us which wont break the bank , and the products that jim & Thanos (Greekbots ) and Ian At Built For Fun are using are a very good way to go .. check out their Websites

Which of those big motors would we want to use?

[nexarone]

Thanks for the motor requirement details. Unfortunately the cost is way out of my budget.

I am considering pneumatic rotary actuator instead of electric motor. Would anyone care to comment? Might be a cheaper option, maybe?

Another interesting electric actuator I was looking at is ServoRam. This is a pneumatic/electric hybrid cylinder ram. Can't find much info, however. No idea about the price of one. No doubt will be expensive. It uses compressed air to support the payload and an electric linear actuator to drive high load with great efficiency and precision. Interesting concept.

Here you have it in detail :
So roughly you can build a 3DOF motionbase with these industrial motors for a weight to 600 kgs for about 5000 Euro.

Hi nexarone,

You should have a look at the following site if you want something really cost effective that might solve your problem!!

Hi Prof Bill,

Yes I have seem that. Great site. I'm looking forward to his 3dof platform plan. Unconventional design I must say. Cheers.

Hi,

what do you guys think about 1000-1200Watt DC scooter motors.
http://www.cn-dcmotor.com/productSho...?ArticleID=277
Connected to a 1:60 reduction made of DIY pulleys, which translate those 4000rpm to 1rps and ~190Nm, and a lever which is connected to a platform.

Reliable solution, or just another toy, what do you think?.

I've sent a request to the manufacturer, and got a quote.

780 USD including shipping for 10pcs 1000W 36-48V motors (they have different models) -> 78 USD/motor.

Neat price, I think.

Regards
Christian

Wheelchair motors ROCK! They dont have the speed some others do, but you dont need that much speed anyway. They DO have huge amounts of torque and can move mountains. And they are only 12 volt DC.
