Description

Technical Field

[0001] The utility model relates to the field of three-phase asynchronous motors, in particular to a high-temperature-resistant and moisture-proof three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor that is powered by a 380V three-phase AC current (with a phase difference of 120 degrees). Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque, realizing energy conversion.

[0003] High-temperature and moisture-proof three-phase asynchronous motors are special motors designed to operate stably under extreme environmental conditions. During operation, the motor generates heat due to the passage of current. If the heat dissipation efficiency is low, the heat cannot be dissipated in time, which will cause the internal temperature of the motor to rise. In a high-temperature environment, the resistance of the motor increases and the performance of the magnetic material decreases, thereby reducing the output power and efficiency of the motor. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, since heat is generated when current passes through, if the heat dissipation efficiency is low, the heat cannot be dissipated in time, which will cause the internal temperature of the motor to rise. In a high temperature environment, the resistance of the motor increases, the performance of the magnetic material decreases, and the output power and efficiency of the motor are reduced. The utility model proposes a high temperature and moisture-proof three-phase asynchronous motor.

The end cover and the sealing shell are detachable to facilitate later maintenance. The heat sink in the heat dissipation mechanism can adopt copper metal material, which can effectively absorb the heat generated by the motor body.
