ABSTRACT:
In a brushless DC motor of the type having a control circuit and a plurality of position sensors, an error detector responsive to the position sensors is used to generate an error signal useful in shutting off the motor. The output signals of the position sensors provide a numerical code representative of the rotation of the rotor relative to the windings. When the numerical code deviates from a predetermined sequence, the error detector generates an error signal and the control circuit shuts off the motor.
