Problems solved by technology

[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 larger the excitation current, and the lower the efficiency and power factor.
The semi-closed slot structure is equivalent to increasing a part of the air gap, which will deteriorate the performance of the motor

Abstract

The invention discloses a stator notch structure, which uses a connecting channel to connect at least two independent stator slots to form a combined slot, and multiple stator slots in each combined slot share the notch of a single stator slot, thereby reducing the The number of notches, thereby reducing the size of the stator notch, reducing the air gap between the motor stator and rotor; this design can reduce the starting current, reduce stray loss, reduce the excitation current, increase the power factor, and can Improve motor efficiency. The invention also discloses a motor using the above stator notch structure. The invention also discloses a compressor using 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 notch 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 stator notch structure, which solves the influence of a large number of notches in the stator on the performance of the motor. [0004] The present invention also provides a motor using the above stator notch structure. [0005] The present invention also provides a compressor using the above motor. [0006] To achieve the above o...
