Abstract

The invention relates to a permanent magnet motor, which comprises a motor casing, a motor front end cover, a motor rear end cover, a rotating shaft, a stator, a rotor, a front bearing, a rear bearing, a corrugated gasket, an encoder, a motor connector and an encoder connector, and is characterized in that the rotor sleeves the rotating shaft, the stator is arranged outside the rotor in a sleevingmanner, the front bearing and the rear bearing are installed at two ends of the rotating shaft, the motor front end cover and the motor rear end cover are respectively connected with the motor casing, the motor connector is installed on the motor casing, the encoder is connected with the encoder connector, and the corrugated gasket is installed between the front bearing and the front end cover. Compared with the prior art, the permanent magnet motor has the advantages of simple process, no bearing clearance, high reliability and the like.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a permanent magnet motor. Background technique [0002] Servo motors are now widely used in the industrial field. Most of the existing servo motors are 8-pole motor cogging, and the cogging torque is relatively large. When the rotor magnetic steel is installed, the poles need to be wrong, which makes the production process complicated. In addition, the motor bearing uses a fixed rear bearing, and the front bearing is fixed with a corrugated washer, and the gap between the bearings is relatively large. The entire sheet of insulating paper is used for the insulation between the single lobe of the stator of the motor, and the process required for installing the insulating paper is relatively difficult. The pin crimping wire of the motor connector is connected to the ground by screws, which may cause problems such as poor grounding. Contents of the invention [0003] The object o...
