High and low voltage of three-phase asynchronous motor

High and low voltage of three-phase asynchronous motor

Three phase asynchronous motors have high requirements for the stability of power supply voltage. High or low voltage can have a significant impact on the operation of the motor, manifested as follows: difficulty in starting, risk of overheating and damage, frequent voltage fluctuations may cause motor vibration, increased noise, and even damage to bearings and seals, overheating and insulation damage, mechanical damage, high voltage may cause arc discharge, damage to the motor casing or surrounding equipment
