Scanning for Ideas: Spindle drive moves with accuracy
The BS22-1.5 spindle drive from MICROMO, Clearwater, Fla., a member of the Faulhaber Group, uses ball screws to generate highly accurate linear motion. The stainless-steel drive is accurate to within 5 micrometers or less over its entire length of travel. The motor connects to the ball screw through a backlash-free coupling that is part of the ball screw.
The screw is 126.5-mm long, and the standard stroke measures 94„mm. Pitch is 1.5 mm. Axial load capacities are to 519 N (dynamic) and 475 N (static). The device can handle input speeds up to 5,000„rpm and still maintain its accuracy.
