Abstract:
1. A motor control system, comprising: a motor housing; an electric motor at least partially disposed within the motor housing, the electric motor configured to be selectively energized and responsive, upon being selectively energized, to rotate; a rotational sensor disposed within the motor housing, the rotational sensor configured to sense rotational speed and position of the electric motor and supply a rotational sensor signal representative of the sensed rotational speed and position; a temperature sensor disposed within the motor housing, the temperature sensor configured to sense a temperature of the electric motor and supply a temperature signal representative of the sensed electric motor temperature; an electrical-to-optical (E/O) converter circuit disposed within the motor housing, the E/O converter circuit coupled to receive the rotational sensor signal and the temperature signal, the E/O converter configured, upon receipt thereof, to convert the rotational sensor signal and the temperature signal to an optical rotational sensor signal and an optical temperature signal, respectively; and a fiber optic cable coupled to receive and propagate the optical rotational sensor signal and the optical temperature signal.
