Embodiment 1

[0049] Such as figure 1As shown, the first embodiment of the present invention proposes a motor, including: a stator 102, a locking device 104, a rotor and a crankshaft.

[0050] Among them, such as figure 2 and image 3 As shown, the locking device 104 is provided with a protruding structure 106, and the locking device 104 is configured to abut against the axial end surface of the stator 102 through the protruding structure 106; the rotor at least partially extends into the interior of the stator, and can It rotates under the drive of the stator; the crankshaft is connected with the rotor and can rotate under the drive of the rotor.

[0051] That is to say, during the working process of the motor proposed in this embodiment, the locking device 104 can apply pressure toward the axial end surface of the stator 102 through the protruding structure 106, which can avoid the radial deformation of the stator 102 during the working process, thereby effectively reducing the The re...

Embodiment 2

[0054] Such as figure 1 As shown, the second embodiment of the present invention proposes a motor, including: a stator 102, a first locking device 104a and a second locking device 104b.

[0055] Among them, such as figure 1 , figure 2 and image 3 As shown, the first locking device 104a and the second locking device 104b are both provided with a protruding structure 106, and the first locking device 104a is configured to abut against the upper axial end surface of the stator 102 through the protruding structure 106 , the second locking device 104b is configured to abut against the lower axial end surface of the stator 102 through the protruding structure 106 .

[0056] That is to say, during the working process of the motor proposed in this embodiment, the first locking device 104a and the second locking device 104b abut against the two axial end faces of the stator 102 from above and below the stator 102 respectively, from The upper and lower directions of the stator 102...

Embodiment 3

[0061] Such as figure 1 As shown, the third embodiment of the present invention proposes a motor, including: a stator 102 and a locking device 104 .

[0062] Wherein, the stator 102 includes a stator punching sheet, and a plurality of stator punching sheets are stacked and distributed along the axial direction of the stator 102; as figure 2 and image 3 As shown, the locking device 104 is provided with a protruding structure 106 , and the locking device 104 is configured to abut against the stator punching plate at the end through the protruding structure 106 .

[0063] The protruding structure 106 of the locking device 104 abuts against the stator punching sheet at the end, and the protruding structure 106 presses the stator punching sheet at the end under the trend of external force, making the stator punching sheets more compact and avoiding the stator punching sheet The relative movement between them, thereby avoiding the radial deformation of the stator 102, avoiding t...

Abstract

The invention provides a motor, a compressor and refrigeration equipment, and the motor comprises: a stator; a locking device which is provided with a protruding structure, wherein the locking device is configured to abut against the axial end face of the stator through the protruding structure. a rotor, wherein at least part of the rotor extends into the stator, and the rotor can be driven by the stator to rotate; and a crankshaft which is connected with the rotor and can be driven by the rotor to rotate. According to the motor provided by the invention, the radial deformation of the stator is limited through the locking device provided with the protruding structure, resonance can be prevented from being generated in the working process of the motor, electromagnetic noise caused by electromagnetic radial force waves is effectively inhibited, and working noise of the motor, especially the electromagnetic noise generated by resonance, is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a motor, a compressor and a refrigeration device. Background technique [0002] During the use of the motor, the deformation of different orders of the stator has different natural frequencies. When the frequency of the radial force wave is close to or equal to a certain natural frequency of the stator, resonance will be caused. At this time, even if the amplitude of the radial force of the stator is not large, it will cause deformation of the stator, periodic vibration, etc., and generate large electromagnetic noise, which will affect the use of the motor and respond to the service life of the motor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] To this end, the first aspect of the present invention provides a motor. [0005] A second aspect of the present invention pro...
