    Hey folks

    i am planning to build my own 6dof -linear actuators- rig and the main point which will define the work path is the BLDC motors as those are significantly expensive and not available unless ordered online, so i was looking for cheaper alternatives:

    1- Stepper 12 Nm with 1:10 gearing to achieve 3000 rpm while keeping a decent amount of torque
    2- Stepper and rail gear sliding mechanism
    3- Old hoverboard BLDC motors with 1:4 gearing to get the same speed
    4- Cheap BLDC like this one https://hongjunst.en.alibaba.com/pr...ml?spm=a2700.icbuShop.41413.13.658036b68yc7of

    and if i am running low on budget should i go for rotating actuators stewart platform instead of linear actuators as i had some doubts of how immersive the experience would be with rotating stewart comparing to linear one

    please let me know your point as selecting the motor is the starting phase for the planing and drawings for the project

    hoverboard motors are worth a try imo
