Abstract

An electromechanical actuator includes an electric motor and a control and drive circuit mounted integrally with the electric motor. The control and drive circuit includes a serial-to-parallel converter for converting a control signal in the form of serial data into parallel data, and a device responsive to the control signal in the form of parallel data for producing a drive current or voltage for the electric motor. A system for accessing or controlling a plurality of such actuators by commands from a main controller can include a control and drive circuit which is integral with the motor itself.
