Problems solved by technology

[0002] It is pointed out in the related art that in the permanent magnet synchronous external rotor motor, the outer diameter of the motor stator is smaller than the inner diameter of the rotor, and the rotor is connected to the shaft through the end cover. The temperature rise can also increase the oil passage area. However, after the oil passage hole is opened on the end cover, the rotor rotation will increase the wind resistance, reduce the motor power, and generate aerodynamic noise. When the motor is used in the compressor, it will Detrimentally affects the performance of the compressor and makes the compressor noisy

Abstract

The invention discloses a rotor end cover of an outer-rotor-type motor. At least an oil passing hole is formed in the rotor end cover. Each oil passing hole deviates from the center of the rotor end cover to the edge of the rotor end cover relative to the radial direction of the rotor end cover. Through arrangement of oil passing holes with a shape similar to a blade in the rotor end cover, wind resistance and noise during rotation of the rotor end cover are lowered.

Description

technical field [0001] The invention relates to the field of motor equipment, in particular to a rotor end cover of an outer rotor type motor and an outer rotor type motor with the same. Background technique [0002] It is pointed out in the related art that in the permanent magnet synchronous external rotor motor, the outer diameter of the motor stator is smaller than the inner diameter of the rotor, and the rotor is connected to the shaft through the end cover. The temperature rise can also increase the oil passage area. However, after the oil passage hole is opened on the end cover, the rotor rotation will increase the wind resistance, reduce the motor power, and generate aerodynamic noise. When the motor is used in the compressor, it will It will adversely affect the performance of the compressor and make the compressor more noisy. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. ...
