Hello,
I have an ongoing design that incorporates somarily into mechanical design, background in CNC. I'm not an electrical engineer but understand electrical principles. I've designed a large apparatus, which does not require precise locationing. Its quite a heavy mass, however it is fully counterbalanced, so the motor only has to overcome the friction of moving it, and holding position. It drives a roller screw mechanism, with 2 fixed points at each end. Two of these actuators work on the fulcrum end of the counterweight, and the entire mass rotates within the center of a large spherical bearing that is either oil, or pneumatically lubricated (tbd). Between the two actuators the mass is able to position the central axis +/- 20 degrees. However the total mass is approx 30,000 pounds including the counterweight. The spherical bearing point in between is around 70" in diameter. The actuator screws are 2" dia. Any suggestions? Hydraulics are not an option because of noise, heat, and leakage.
