Technical Field

The invention relates to the technical field of motor rotors, in particular to a grinding device of a motor rotor.

Background

The rotor of an electric machine is colloquially said to be the rotating part of the electric machine. The motor consists of a rotor and a stator, and is a conversion device for realizing electric energy and mechanical energy and electric energy. The fixed part in the motor is called a stator, and a pair of DC excitation static main magnetic poles are arranged on the stator; the rotating part (rotor) is called an armature core, an armature winding is arranged on the rotating part, and after the armature core is electrified, induced electromotive force is generated to serve as a rotating magnetic field. Then electromagnetic torque is generated to carry out energy conversion. The shape of the stator winding is distinguished from the embedding mode, and the stator winding can be divided into a centralized type and a distributed type according to the difference between the winding shape of the coil and the embedding wiring mode. The rotor of the motor is divided into a motor rotor and a generator rotor. The motor rotor is divided into an inner rotor rotation mode and an outer rotor rotation mode. The inner rotor rotates in such a way that a core body in the middle of the motor is a rotating body, and torque (referred to as a motor) is output or energy is input (referred to as a generator). The outer rotor rotation mode is that the motor outer body is used as a rotating body, and different modes are convenient for application in various occasions.

The rotor of the brushless direct current motor is formed by embedding permanent magnets with certain pole pairs on the surface of an iron core or in the iron core. The permanent magnet is mainly made of rare earth permanent magnet materials with high coercive force and high permeability magnetic induction density, such as neodymium iron boron. The action of the permanent magnetic steel of the rotor is similar to that of the permanent magnetic steel used by the brush motor, and an enough magnetic field is established in the air gap of the motor. The rotor structure of the brushless dc motor mostly adopts a surface-bonded magnetic pole, also called a tile-shaped magnetic pole. The surface-pasted magnetic pole is that the tile-shaped rare earth permanent magnet magnetized in the radial direction is pasted on the outer surface of the iron core, and the air gap flux density in the form of square waves can be obtained through reasonable design.

At present, the internal groove of the motor rotor is polished manually, and the internal groove of the motor rotor is narrow in space and large in internal space of an external opening, so that polishing is very difficult, polishing efficiency is low, and operation difficulty of workers is high.
