ABSTRACT:
A rotary direct drive servovalve having a force motor which includes a rotor assembly positioned within an isolation tube which is surrounded by a stator assembly. A permanent magnet is disposed adjacent a closed end of the isolation tube and is rotatable to position the rotor at a desired predetermined position by interaction of magnetic forces between the permanent magnet and permanent magnets disposed upon the rotor. The permanent magnet is clamped in position subsequent to adjustment to thereby provide centering forces on the rotor.
