ABSTRACT:
A rotary actuator for a microwave switch, including, a stationary armature formed by a core positioned along a particular axis and with a coil wound around the core to form at least one electromagnet and with the polarity at the end of the core in accordance with the direction of current flow through the coil upon the application of electrical energy to the coil, a rotor positioned adjacent to one end of the core and with the rotor supported for rotation in a plane perpendicular to the particular axis of the core, the rotor including a plurality of spaced permanent magnets located axially relative to the one end of the core and with the application of electrical energy to the coil providing axial excitation to produce magnetic interaction between the permanent magnets and the core and provide rotary travel of the rotor in one of two opposite directions in accordance with the direction of current flow through the coil, and a stop located in the path of rotation of the rotor to engage a portion of the rotor to limit the travel of the rotor between fixed positions.
