[0004] 1. The existing shaded-pole motor rotor and stator are usually limited by bolts and nuts. The use of bolts and nuts requires specific design of bolts and nuts according to the model of the equipment, and the fault tolerance rate is low. After long-term operation, a certain degree of shaking occurs between the rotor and the stator, resulting in increased wear between the rotating shaft on the rotor and the stator. Failure to add lubricant in time can easily reduce the life of the motor.

The noise generated by the motor is mainly based on the shaking caused by the rotation of the motor. The motor shakes more and more after long-term operation. There is no corresponding alarm mechanism to remind users that timely maintenance is needed, which leads to an increase in the heat generated by the shaded-pole motor during operation. In severe cases, a short circuit may occur, or even a fire may occur.

[0018] The technical solution provided by this application has at least the following technical effects or advantages:

[0019] 1. The use of a fastening assembly effectively solves the problem of conventionally using bolts and nuts to limit the rotor and stator of existing shaded-pole motors. The use of bolts and nuts requires the design of specific bolts and nuts according to the model of the equipment, and has a low fault tolerance rate. A certain degree of shaking occurs between the rotor and the stator during long-term operation, resulting in increased wear between the rotating shaft on the rotor and the stator. Failure to add lubricant in time can easily lead to a reduction in the life of the motor. The present invention can limit the connection between the rotor and the stator through a fastening assembly, and can adapt to motors of various specifications. At the same time, when the stator and rotor of the motor shake, lubricant can be applied to the rotating connection in time, thereby reducing the wear of the rotating shaft and other components and increasing the service life of the motor.

[0020] 2. The use of protective components effectively solves the problem that the existing shaded-pole motor generates large noise during operation, affecting the user experience. The noise generated by the motor is mainly based on the shaking caused by the rotation of the motor. The motor shakes more and more during long-term operation. There is no corresponding alarm mechanism to remind the user that timely maintenance is required, which leads to an increase in the heat generated by the shaded-pole motor during operation. In severe cases, a short circuit may occur, and even a fire may occur. The present invention can reduce the shaking generated by the motor during operation through the protective component, reduce the noise generated during operation, and improve the user experience. At the same time, when the shaking amplitude reaches a certain level, an alarm can be issued in time to remind the user to perform maintenance and avoid dangerous situations such as short circuit of the motor.

[0021] 3. The use of a limiting component effectively solves the problem that the existing shaded-pole motor winding has poor fixing effect. The winding is covered with copper wires. During the operation of the motor, the copper wires touch other components due to the poor winding fixing effect, which makes the shaded-pole motor have safety hazards during operation. The present invention can fix the motor winding on the stator through the limiting component, prevent the copper wires on the winding from touching other components, and reduce the probability of safety hazards in the shaded-pole motor during operation.

DETAILED DESCRIPTION

[0037] When the rotor and stator work for a long time, a certain degree of shaking occurs between them, which leads to increased wear between the rotating shaft on the rotor and the stator. Failure to add lubricant in time can easily lead to a shortened motor life. The present invention can apply lubricant to the rotating connection in time when the stator and rotor of the motor shake, thereby reducing the wear of the rotating shaft and other parts through the fastening assembly. The shaded-pole motor generates a large noise during operation, which affects the user experience. The present invention can reduce the shaking of the motor during operation through the protective assembly, reduce the noise generated during operation, and improve the user experience. When the copper wire touches other parts due to poor winding fixation during motor operation, the present invention can fix the motor winding on the stator through the limiting assembly, thereby preventing the copper wire on the winding from touching other parts.
