Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an induction motor with an anti-detachment structure. Background Technology

[0002] An induction motor, also known as an asynchronous motor, is a device in which the rotor is placed in a rotating magnetic field. Under the action of the rotating magnetic field, the rotor obtains a torque, thus causing the rotor to rotate.

[0003] An asynchronous induction motor with a high heat dissipation structure is disclosed in publication number CN212366987U. Although this utility model sets up a heat absorption pump and a heat absorption pipe, with the heat absorption pump fixed inside the base and the heat absorption pipe at the top of the heat absorption pump connected to the bottom of the induction motor body, when the induction motor body is working, the heat absorption pump absorbs the heat inside the induction motor body through the heat absorption pipe. The heat absorbed inside the heat absorption pipe enters the interior of the base and is then discharged to the outside through the heat dissipation pipe, which facilitates the dissipation of heat inside the induction motor body and thus increases the practicality of the asynchronous induction motor.

[0004] However, this high-heat-dissipation asynchronous induction motor has the following disadvantages: the direction of the junction box outlet is difficult to change, which is not conducive to on-site wiring, resulting in unnecessary bending of the connecting cables and making it difficult to improve installation adaptability. In addition, the motor itself will generate electromagnetic vibration and mechanical vibration during operation, and when the motor rotates at high speed, the fan will be subjected to huge centrifugal force. Long-term and severe vibration will cause the fan to fall off the motor shaft, making it difficult to ensure the performance of the induction motor. Utility Model Content
