Abstract
An actuator () comprises a rotor (); an electromagnetic circuit () configured to produce bidirectional torque on the rotor; and, a rotation limitation assembly (). The rotor () comprises a rotor shaft and plural magnets () affixed to the rotor shaft. In an example embodiment the rotation limitation assembly () comprises at least one stationary clockwise boundary () configured to limit clockwise rotation of the rotor (); at least one stationary counterclockwise boundary () configured to limit counterclockwise rotation of the rotor (); and a rotor stop arm () connected to the rotor and configured to selectively abut the clockwise boundary () and the counterclockwise boundary () and thereby limit the rotation of the rotor to a predetermined angle about an axis of the rotor shaft.
