Monitoring system of motor running states

The utility model discloses a monitoring system of motor running states, including two inductors, controlling means and output device, two inductor and output device are connected two with the controlling means electricity respectively the peripheral plane that just is located same perpendicular to motor shaft axle center at motor shaft is all established through support ring to the inductor, motor shaft is last to be equipped with an induction point, the induction point rotates along with motor shaft, wherein, two the contained angle that the line formed between inductor and the motor shaft axle center is a, and 0 < a < 180. This system can judge motor shaft's running state rapidly, and when motor shaft was rotatory, the last induction point of motor shaft was corresponding with two inductors respectively in turn in proper order along with the direction of rotation of pivot, and the signal was sensed in proper order to two inductors this moment, determined the direction of motor shaftrotation to the time tha
