New AC Servo Actuator from Harmonic Drive

The new SHA brushless servo-actuator provides the highest torque density of any actuator in its class. Positional accuracy better than 1 arc-min and ±5 arc-sec repeatability is achieved while delivering up to 30,000 in-lb of torque. A robust cross-roller bearing allows mounting of large loads directly to the actuator without additional support. The SHA Series actuator also features a compact, hollow shaft configuration that allows design versatility for demanding applications.
