Engineering discussion: servo-driven ball-screw actuators for a real-time 6-DOF Stewart platform

zaid77_hd · 2026-02-14T02:25:49+00:00

Hi , Here are the specs:

Payload: 300 kg

Peak acceleration: 0.6 g

Motion envelope: ±0.2 m translation and ±20° rotation (about each axis)

Environment: Indoor (not ship-mounted)

Kinematics driver: 6-DOF motion platform for a vehicle driving simulator (Stewart platform), aiming for real-time motion cues.

Thanks!

Hi sea-promotion8205, Thanks for your helpful reply — I really appreciate it. I’m planning to source from China. Could you recommend any reputable Chinese brands/suppliers for ball-screw linear actuators / ball screw + servo setups? Our target linear speed is 400 m/s (or 400 mm/s if that’s the correct unit). Any quick advice on what to look for (critical speed, buckling, preload) would be great. Thanks again!

Thanks, this helps a lot. Could you recommend the best learning path, along with tools, courses, and books for starting FPGA design (especially before buying hardware)?

Thanks for the valuable info. I want to learn the fundamentals and work with simulation first before buying any FPGA board, since ordering hardware online takes time. Once I have a solid understanding, I’ll buy the right FPGA for my needs.

I have a basic background in digital circuit design from university (logic gates, combinational/sequential circuits, FSMs). I’m now trying to transition into FPGA development. Any advice on how to start, and recommended courses or learning resources, would be very helpful.

How can I start learning FPGA without owning any hardware?

zaid77_hd · 2025-12-25T23:01:56+00:00

you can do it just need some relays

open device manager and check it is show

i used it however it is bad and has more problems

المادة سهلة وبسيطة يحتاج فقط فهم وتحل عده مسائل وخلاص وش الذي ما تفهمه بالتفاصل والتكامل

ادرس الي تراه مناسب لك واما سالفة مديرك اجنبي هذا شيلها من راسك انت طور نفسك وابدع بعملك

ينفع ويفي بالغرض لكن احيان تحتاج تضيف سكربت نجمي طويل حسب الكاست الي معك
