Tips: Induction motor’s applications
Induction motor is an AC motor whose ratio between loaded rotate speed and the frequency connected to the grid is not constant. It varies with the size of load. The larger the load torque is, the lower the rotor speed is.
Induction motor, mainly running as an electric motor with the power range from a few watts to thousands of kilowatts, is the most widely used to provide power for a variety of mechanical equipment and household appliances. Three-phase induction motor are mostlt used to drive machine tools, small and medium steel rolling equipment, fans, pumps, light industry machinery, metallurgy and mining machinery etc.Single-phase induction motor is widely used in fans, washing machines, refrigerators, air conditioners and other household appliances. Induction motor can also be used as the generator for wind power plants and small hydro-power stations.
