Abstract

The invention provides a stator fixing device, a compressor and a motor, the stator fixing device comprises a stator iron core (11), a shell (2) and a cover body (3), the stator iron core (11) is arranged in the shell (2), the outer peripheral wall of the stator iron core (11) is connected with the inner peripheral wall of the shell (2), and the cover body (3) comprises a main body part (31) and an extension part. The extension part (32) is connected with the main body part (31), the main body part (31) covers and is fixed at one end of the shell (2), and the extension part (32) extends into the shell (2) and abuts against one end of the stator iron core (11). According to the invention, the axial vibration of the stator can be restrained, the rigidity of the stator is improved, the vibration amplitude of the stator is reduced, the vibration propagation and noise radiation of the stator are reduced, the noise of the rotary compressor is effectively reduced, and the noise quality of therotary compressor is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a stator fixing device, a compressor and a motor. Background technique [0002] One of the vibration and noise sources of the rotary compressor is the exciting force of the motor, that is, the magnetic field is generated after the stator coil of the motor is energized, and the rotor of the motor rotates under the action of the electromagnetic force of the stator coil, and the opposite rotor also produces a reaction force on the stator, thus cause the stator to vibrate. The stator of the motor is fixed inside the casing of the rotary compressor by pressing, welding, etc., so the vibration of the stator will be transmitted to the casing, so that the entire rotary compressor will vibrate and radiate noise outward. [0003] Since the stator of the rotary compressor motor in the prior art is prone to vibration, resulting in relatively large noise and other problems, the present i...
