The working principle of the three-phase asynchronous motor is based on the principle of electromagnetic induction and work, when the stator winding through the three-phase symmetrical alternating current, the rotating magnetic field between the stator and the rotor is generated, the rotating magnetic field cuts the rotor winding, generates induction electromotive force and current in the rotor loop, the current of the rotor conductor under the action of the rotating magnetic field, subjected to the force and make the rotor rotate.
What is a three-phase asynchronous motor?
Three-phase asynchronous motor is a kind of induction motor, it is a kind of motor powered by 380V three-phase AC power supply at the same time, because the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called three-phase asynchronous motor.
The application range of three-phase asynchronous motor?
Three-phase asynchronous motor is the leading product of small and medium-sized motors. As one of the most important power equipment, it converts electrical energy into mechanical energy and drives all kinds of machinery and equipment. It is widely used in chemical, textile, metallurgy, construction, agricultural machinery, mining, light industry and other industries. A large number of fans, pumps, compressors, machine tools, printing presses, light rail traffic and mine electric vehicles and other major mechanical drive power source.
What is the difference between three phase and single phase?
1. The three phases are the 3 fire lines indicated as L1, L2, L3, and the middle line indicated as N; The single phase is 1 live wire and 1 neutral wire, marked L and N;
2, the single-phase power supply voltage is 220VAC, usually used at home or school; The three-phase power supply voltage is 380VAC, which is used by general enterprises, factories and other places.
