Description

Technical Field

[0001] The utility model belongs to the technical field of motor end covers, and particularly relates to a front end cover component. Background Art

[0002] The motor, commonly known as "motor", refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is composed of a stator, a rotor, a magnetic field, a winding, a bearing, an end cover and a casing. The front cover of the motor can protect the internal components of the motor from external damage, reduce the frequency of maintenance and extend its service life. However, most common front covers of motors do not have a heat dissipation structure. Most of their heat dissipation structures are set at the rear shell of the casing. During the operation of the motor, heat will be generated at both ends. If heat can only be dissipated through the rear shell, the heat dissipation effect of the motor will be reduced, making the operating temperature of the motor higher. The operation of its internal components in a high temperature environment will reduce the performance of the motor, affect its normal working state, and increase the power consumption, which will increase the cost of use.

[0003] Secondly, the high operating temperature of the motor will also accelerate the aging of internal components, increase the frequency of motor maintenance and reduce its lifespan.

[0004] In addition, overheating may cause the motor bearing lubrication to fail, increase wear, and even cause the bearings to burn or lock, affecting the rotation stability of the motor.

[0005] In summary, the lack of a heat dissipation structure on the front end cover of the motor will affect the heat dissipation effect of the motor, thereby causing some usage problems. Therefore, it is hoped that a new structure will be proposed to solve the above technical problems. Utility Model Content
