Compressor, motor and stator punching sheet structure

Abstract

The invention discloses a stator punching sheet structure. On the basis of a general stator punching sheet structure, each of stator slots is divided into two parts (two parts share one winding installation channel, and the part of stator slots connected via connection channels serves as one part), the two parts share the same winding installation channel, and the stator slots in each part are connected through the connection channels, winding installation is conducted through one winding installation channel, welding is performed at stator core welding points after winding installation is finished, and thus the intensity of a stator core is ensured. According to the above structure, stator notches are removed, so the influence of notches upon a stator is avoided; starting currents are minimized, stray loss is reduced, excitation currents are reduced, the power factor is increased, and the motor efficiency is improved by means of such a design; and the stress intensity of the stator itself is improved after welding at the welding points are finished. The invention also discloses a motor applying the above stator punching sheet structure. The invention further discloses a compressor applying the motor.

Description

technical field [0001] The invention relates to the technical field of motor stators, in particular to a compressor, a motor and a stator stamping structure thereof. Background technique [0002] Generally, the air conditioner compressor motor stator has a semi-closed slot structure, and the larger the air gap between the motor stator and rotor, the greater the excitation current, and the efficiency and power factor will decrease. The semi-closed slot structure is equivalent to increasing a part of the air gap, which will deteriorate the performance of the motor. Contents of the invention [0003] In view of this, the present invention provides a stamping structure of the stator, which solves the influence of the presence of slots in the stator on the performance of the motor. [0004] The present invention also provides a motor using the above-mentioned stator stamping structure. [0005] The present invention also provides a compressor using the above motor. [0006] ...
