A boom deploy actuator with improved maintainability and simplicity has an electric motor and control circuitry for selectively powering the motor to develop torque with either rotational direction for rotating a capstan to vary the length of a boom cord extending from the capstan to a boom. In a preferred embodiment, the motor is a brushless electric motor. The control circuitry preferably includes circuit components for limiting the speed of the motor.
