Embodiment Construction

[0009] The present invention is mainly composed of the stator iron core punching sheet 3, the virtual slot opened on the pole shoe at the bottom of the stator iron core punching sheet 3, and the like.

[0010] Depending on the number of poles of the motor, 1 to 3 virtual slots can be opened, for example, a virtual slot 1 is opened at the center of the pole shoe at the bottom of the stator core punch 3 of an 8-pole machine, and at the bottom of the stator core punch 3 of a 6-pole machine Two virtual slots 2 are evenly opened on the pole piece. During processing, first make a mold according to the design requirements, and then punch out the required punching sheet. During the punching process, through equipment control, the required stator core is automatically laminated.

Abstract

The invention relates to a low noise stator core lamination and belongs to the field of manufacturing technology of matching parts used by a motor. The low noise stator core lamination is mainly composed of a stator core lamination (3) and a virtual groove which is opened on a pole piece at the bottom of the stator core lamination (3); 1-3 virtual grooves are opened according to the different number of the motor. The lamination has reasonable design and simple structure; the virtual grooves are added on the pole piece of the stator core to lead the frequency of slot ripples to be higher and the amplitude to be lower by taking steps on the inner parts of the motor, thus lowering the noise on the whole, improving the running noise of the motor effectively and improving the product quality.

Description

technical field [0001] The invention relates to a low-noise stator iron core punching sheet, which belongs to the technical field of manufacturing matching parts for motors. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quietness of air conditioners, and part of the noise of air conditioners comes from the operation of motors. There are many sources of noise from motors. In order to reduce the noise generated by motors, most of the existing technologies By finding a solution on the motor rotor, mounting feet and other components, for example, Chinese patent ZL200720105627.9 provides a mounting bracket for reducing motor noise. But there is no improvement report from the stator structure. Contents of the invention [0003] The purpose of the present invention is to provide a low-noise stator core punching plate with reasonable design and simple structure, which can effectively improve the running ...
