Hi guys, I hope I don't duplicate another thread. I've been looking for the info on the forum but none seem to match.
I'm looking at the possibility of making my 6DOF platform using linear actuators. Any body has experience regarding those? My quest is to find the simpler and cheaper solution for my simulator without compromising on quality. By putting linear actuators, I can get rid of VFDs, motors and gearboxes...right?!?
I don't want to reinvent the wheel here, but just asking the reason nobody seem to consider the avenue.
Regards.
Patrick

Hi ,
Most of our sim rig are builded with asynchrone Motors (AC motors) and gearboxes and the cheapest mounting is to use just an arm level to lift the load. The gearbox ratio is about from 75 to 100 for a motor nominal speed at 1400 rpm ( 4 poles motor) .A good output gearbox speed is also from 10 to 25 rpm.
For linear actuators with or not gearbox , depends on the final ratio and motor torque , the motor used is often a synchrone motor . High motor speed , dynamic etc..
Th difference between is the price for the motors and all stuff needed to build a linear actuator, pulleys , belts , etc...
For now I not yet seen a DIY 6dof with those motors.There is on the he french forum racingfr.com a guy which is working on building a linear actuator for building his 6dof.
If you have an interest I can give here the link , but you have to use translator to undertand , except if you are french ;-)
