Steinmeyer's mini actuator provides ultra precision in a small package.
Steinmeyer, Inc. announced a miniature precision actuator that doesn’t require external bearings or couplings. The actuator includes a precision ball screw, a Faulhaber DC motor with graphite commutation and a gearless coupling for high speed, backlash free positioning and high performance in drive motion controller.
The actuator is available in travels ranging from 10-300 mm, resolution of 1 micron with integrated rotary encoder, speeds up to 120 mm/s, axial loads up to 800 newton. Options include Steinmeyer ball screw with alternate diameter and pitch (standard is 8 mm diameter with 2 mm pitch).
