Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a multi-winding overheat-proof motor. Background Art

[0002] An electric motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction.

[0003] In a noise reduction and heat dissipation motor with application number CN202021453592.X, a noise reduction and heat dissipation motor is disclosed, including a motor housing, a stator, a rotor and a shaft mounting rod; a stator is welded in the motor housing; a rotor is sleeved in the stator; a shaft is rotatably mounted in the motor housing through a vertical beam; the vertical beam is fixedly mounted in one side of the motor housing; a fan blade is connected to the end of the shaft close to the vertical beam; the fan blade is arranged in the motor housing; a cold air blower is fixedly connected to the side of the motor housing away from the vertical beam through an air guide pipe; the cold air blower is fixedly mounted on the shock absorbing device under the motor housing. The utility model device delivers the cold air produced by the cold air blower to the inside of the motor, and the cold air takes away the heat in the motor when flowing inside the motor, and the fan blades discharge the cold air that absorbs the heat to the outside of the motor, so as to achieve good heat dissipation effect; at the same time, a shock absorbing device is fixedly mounted under the motor, and the shock absorbing device is adjustable, which increases the shock absorbing effect of the shock absorbing device.

[0004] However, when the motor is dissipating heat, a large amount of airflow is required to continuously circulate inside the motor, which causes the airflow to continuously pass through the heat dissipation cover to achieve the heat dissipation function. However, since the air contains a kind of impurity, the impurity will be retained on the inner wall of the ventilation hole when passing through. If this continues for a long time, it will cause the ventilation hole to be blocked, making it difficult for the motor to dissipate heat.

[0005] Therefore, how to provide a multi-winding overheat-proof motor is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0040] By arranging a dust removal structure at the right end of the rotating shaft 5, when the rotating shaft 5 rotates, the dust removal structure will be driven to rotate around the inner and outer sides of the heat dissipation rear cover 6, so that the dust in the heat dissipation rear cover 6 can be pushed out and scraped off, thereby avoiding impurities from being retained in the inner wall of the ventilation hole of the heat dissipation rear cover 6, causing the ventilation hole to be blocked, and affecting the heat dissipation effect of the motor.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the utility model, a cooling structure is provided on the surface of the shell 1, and the cooling structure includes a vent 13, a heat conducting plate 16 and a fan blade 12.
