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 slot opening structure. At least two stator slots are connected by a connection channel to form one jointed slot; and a slot opening of single stator slot is shared by a plurality of stator slots in each jointed slot, so that the number of the slot openings is reduced; the dimensions of the stator slot openings are reduced; and an air gap between a stator and a rotor of a motor is reduced. According to the stator slot opening structure, the starting current can be reduced; the stray loss is reduced; the excitation current is reduced; the power factor is increased; and the efficiency of the motor can be improved. The invention further discloses the motor employing the stator slot opening structure, and further discloses a compressor employing 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...
