ABSTRACT:
A two-position rotary actuator provides a latching or holding torque which can be adjusted by altering the magnetic properties of a selected pole member. The actuator also functions as a sector motor over a selected range of angular motion and provides failsafe operation which returns the actuator to a starting position when electrical power is removed.
