Abstract

The present invention provides a permanent magnet motor rotor protection device which comprises a connecting rod, an outer ring, an outer sliding groove, a ball, an inner sliding groove, a protection ring and a stabilizer bar, the protection ring is mounted on the annular side surface of a rotor main body, the inner sliding groove is formed in the annular side surface of the protection ring, the ball is embedded in the inner sliding groove, and the outer ring is mounted on the outer side of the ball. The inner annular side face of the outer ring is provided with an outer sliding groove, the balls are embedded into the outer sliding groove, the connecting rods are installed between the motor shell and the outer ring, and the stabilizing rod is installed between the connecting rods, the problem that an original permanent magnet motor rotor lacks protection measures is solved through the design, the permanent magnet motor rotor protection device is reasonable in structure, protection is provided for the permanent magnet motor rotor, and abrasion is avoided.

Description

technical field [0001] The invention is a permanent magnet motor rotor protection device, which belongs to the technical field of motor production. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The motor is represented by the letter M in the circuit, and its main function is to generate driving torque. As a power source for electrical appliances or various machines, the generator is represented by the letter G in the circuit. Its main function is to use mechanical energy to convert electrical energy. Among them, the permanent magnet motor is a kind of electric motor. [0003] The existing permanent magnet motor rotor lacks protection measures, and most of the rotors of permanent magnet motors lack protection measures. During the use of the rotor, the rotor of the permanent magnet motor is extremely easy to wear and tear. Now there is an urgent need for a per...
