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

The invention discloses a stator punching structure. On the basis of the normal stator punching structure, the stator slot is divided into two parts (changed to share the same off-line channel, and the stator slot is calculated by connecting the part through the connecting channel). As a part), each part shares one off-line channel, uses the connecting channel to connect the stator slots in each part, and goes off-line through one off-line channel, and welds at the soldering point of the stator core after completion to ensure that the stator core strength; this scheme achieves the removal of the stator notch through the above structure, and solves the influence of the stator notch on the performance of the motor; this design can reduce the starting current, reduce the stray loss, reduce the excitation current, and increase the power factor , can improve the efficiency of the motor; and the stator can also increase its own stress intensity after welding at the solder joints. The invention also discloses a motor using the above-mentioned stator stamping 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 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] ...
