Problems solved by technology

[0002] Shaded pole motors are widely used in many fields due to their simple structure and low cost. However, none of the shaded pole motor products on the market currently have a speed feedback system. If the motor speed is too high, the temperature of the motor will rise and the service life of the motor will be reduced.

Abstract

The invention discloses a shaded pole motor protection system which comprises a motor rotary shaft, a shaded pole motor, a multilevel magnetic ring, two groups of hall sensors and a PCB (printed circuit board). The multilevel magnetic ring is mounted at the end of the motor rotary shaft, the hall sensors are fixed onto the PCB, and the detection face of each hall sensor is away from the surface of the multilevel magnetic ring by 2-4cm. The shaded pole motor protection system has the advantages that rotation speed of the shaded pole motor is monitored and fed back to users, an alarming device can be started when the rotation speed is overhigh, the users can conveniently and timely know service conditions of the motor, faults caused by overhigh rotation speed of the motor can be avoided, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a motor protection system. Background technique [0002] Shaded pole motors are simple in structure and low in cost, and are widely used in many fields. However, none of the shaded pole motor products on the market currently have a speed feedback system. Excessive motor speed will cause the temperature of the motor to rise and reduce the service life of the motor. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the invention is to provide a protection system for a shaded pole motor, which can monitor the rotation speed of the motor, so as to realize the protection of the motor. [0004] Technical solution: A protection system for a shaded pole motor, including a motor shaft, a shaded pole motor, and a multi-stage magnetic ring, a Hall sensor and a PCB. The multi-stage magnetic ring is installed at the end of the m...
