ABSTRACT:
An apparatus for use with a multi-phase brushless DC motor which is driven by signals from a motor controller/driver device, in which power supplied to the motor controller/driver device is routed through a bridge rectifier circuit so that the proper polarity of voltage is supplied to the motor controller/driver device, and also including a circuit connected between a power lead to the motor controller/driver device and input terminal of the bridge rectifier circuit so that a forward/reverse control signal is generated and can be applied to the motor controller/driver to control the direction of rotation of the motor as a function of the polarity of the power supplied to the bridge rectifier circuit.
