Commercial 3DOF Motion Platform Stepper Motor development questions

so I had an engineer help me pick out motors and I wanted to ask do I need everything in the kit for my 3DOF motion platform http://www.omc-stepperonline.com/3-...-ma860h-driverr-kit-for-cnc-router-p-307.html

@noorbeast

I don't think the motors will be strong enough for a motion platform, a seat mover should be fine but not a platform.
At 13NM holding torque I doubt they will have the strength to survive fast directional changes on a full platform motion simulator. 13NM equates to around 132kg for a 1cm lever arm. 3cm is probably the minimum you would want to go for and with that length the motors can only hold 44kg.

Ideally you would want a motor that has been geared down so that it has greater torque. Those steppers appear to have a gearbox option.

One other point is that I don't think that anyone has set up a motion simulator with a stepper motor as they require continual pulses to get them moving as opposed to the more common method of using servomotors. (simple DC motor with feedback). So i am not sure if anyone has coded for the use of stepper motors.

Another maybe non issue is that stepper motors might be uncomfortable especially in low speed motion as you would feel vibrations (each step), especially in the motors listed as the step angle is 1.5 degrees (quite coarse). A grearbox would greatly reduce the vibrations felt.

We are using gear boxes with it, that will supply 50nm, I was asking if the items like the driver and PSU can be used for making the platform @noorbeast @Alexey

here is the gearbox that will be used http://imgur.com/3lHGM7f

your right it is noisy but was that spinning on fast RPM?

if anyone can suggest a better motor to use with the gear boxes i provided then, the Flange needs to be 86*86 square.

@noorbeast about coding, are they saying I wont be able to simulate the games and software?

@noorbeast are there instructions to do this?

@SeatTime who can I get help in the programming part, I still want to move forward with it, as it has been calculated by the engineer. The noise wont be so bothersome for the fact it will be outside

Ok I decided to go with servo motor instead, let me know if this would be the easiest thing to do then? @noorbeast

@marc79 Geez mate, don't you get it? Your "going where no man has gone before" so to speak.
Every reply from the gurus of the forum so far has been negative. Go for it by all means, but realize it's useless asking questions about a subject that has hardly been explored. That's my opinion anyway. At least your slowly building up some coins!! II
ps I even started to wonder if you and you're engineer are fair dinkum, Sorry!!

Im asking about servo motors now, not stepper motors, so your saying no motor but DC motors have not been tried before?

its fine what I can do is make a smaller platoform using servo motors and experiment with that first, I also found me a arudino programmer to help me with the project @noorbeast. I found out servo motors are the best motors to use for motion platform. Seems like no one here has experience with motors. I might show the project once finished, but I am not getting enough here to share with everyone. if this works I would had made a cool 3DOF for pretty cheap. oh and it helps I have a brother in law that works with metals

lol funny guy.

yeah because all I got was negative feedback on stepper motors and when I decided to change motors to Servo motors I get hit with no info again. I would be happy to share if I can get some feedback here. The servo motors im getting now with gearbox, servo driver and cables are costing me 1200 usd and give 65NM of torque on each motor. The engineer from the motor company they have DC motors but servo motors are much better for it as going forward and reverse.

Seatime and Noorbeast have been the most helpful and I appreciate there feedback also it seems I can make it for servo motors http://www.instructables.com/id/ArduinoServoPotentiometer/
