Abstract

This paper investigates the operation of the motor caused by the bearing deflection, we will design detection circuit to detect bearing deflection, the circuit includes coil, rectifier circuit and voltage measuring device. In the interior of the motor, coil has been designed in gap between the stator silicon steel, and then connect a rectifier circuit to an external motor, the rectifier circuit is connected to the voltage measurement terminal. When bearings close to stator silicon steel in the operation of the motor, the induced voltage of the coil will rise and transmit the voltage to rectifier circuit instantly. In this case, the voltage rectifier circuit will convert the DC voltage, the voltage delivered to the voltage measurement terminal, at this time, users can know the motor bearings have deflected phenomenon based on the DC voltage , and can immediately improve motor and maintenance operations.
