Hi I'm martin, I'm reading in this forum for some time now and I want to build my own simulator.
The most important thing is fast and acurate movement for racing games and it shouldn't get too expensive. Some nice people from another forum already helped me with my design.
I will use self-made ballscrew actuators. The ballscrews will be 25mm in diameter 5mm pitch and of 500m length. As motors I consider a zyt90-155 or a zyt90-199 The controller will be two Kangaroo x2 and sabertooth 2x25. The max. platform-angle sould be around 18° with 2 x 40mm up and down movement.
This is the actuator design:
... and this is how I planed the simulator so far:
Do you think the small power of the kangaroo will lift you? Lift you powerfull as usual for simulators? Look at tronics AC motor control, they can and maybe you get some cheap from ebay. It might be easier going for you.
If a answer is correct or did help you for a solution, please use the solve button.
Thank you for your answer. I don't have experience in what is needed to lift a platform.
I found this in the gallery: viewtopic.php?t=273 It's a great work but it doesn't look very snappy.
They use 350W DC motors but ballscrews with 10mm pitch, which need stronger motors and the center of movement is much higher than the center of gravity so the motors have to work very hard. I tried to match both, center and movement and center of gravity.
I have been told in another forum that AC-motors are strong but relatively slow and sluggish in reaction. I would like to have a snappy motion like you can get from scn actuators. Some people said that the AMC does have some slight lag and isn't as fast and accurate compared to a JRK or a Kangaroo and it is fiddly to adjust? I know I can't have everything but maybe I can find a good compromise?
Ballscrews are relatively efficient and easy to hold and move with 5mm pitch and I thought about supporting the left and right actuators with big springs which each can lift 60Kg. The platform inculding me should be 120kg. I don't want use screens but the oculus rift with my simulator, so this saves me some weight.
What do you think about this? Are there fast and snappy AC-solutions in the same price-region of my choosen stuff?
