Problems solved by technology

The motor is basically composed of a casing, a rotor, an end cover, a junction box, etc. The end cover and the casing of the existing motor are fixed by bolts. Since the motor will vibrate during operation, these vibrations will cause the end cover and the casing to The bolts between the bodies are loose, and it makes noise, and it is easy for water to enter, causing damage to internal parts

Abstract

A novel variable-pole multi-speed three-phase asynchronous motor comprises a housing, a rotor, a base, a terminal box, an end cover and a terminal box cover and further comprises a round waterproof rubber ring and a square waterproof rubber ring, wherein the end cover is arranged on the side face of the housing through screws, the rotor is arranged in the housing, the base is arranged at the bottom of the housing, the terminal box is arranged on the outside of the housing, the terminal box cover is arranged on the outside of the terminal box through screws, the round waterproof rubber ring is arranged on the inner side of the end cover, and the square waterproof rubber ring is arranged in the terminal box cover. The novel variable-pole multi-speed three-phase asynchronous motor is simple in structure, reasonable in design and capable of playing a good waterproof role, and noise and damage rate are reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a novel variable-level multi-speed three-phase asynchronous motor. Background technique [0002] The pole-changing multi-speed three-phase asynchronous motor is one of the main derivative series of the Y series three-phase asynchronous motor. It has the characteristics of changing the speed according to the requirements of the load nature, so as to achieve a reasonable matching of power and simplify the speed change system. The motor is basically composed of a casing, a rotor, an end cover, a junction box, etc. The end cover and the casing of the existing motor are fixed by bolts. Since the motor will vibrate during operation, these vibrations will cause the end cover and the casing to The bolts between the bodies are loose, and noise is generated, and water is easy to enter, causing damage to internal parts. Contents of the invention [0003] The purpose of the p...
