We know the three-phase alternating current phase difference120°This is alsoThree-phase asynchronous motorThe reason why it is called "asynchronous" is not called synchronous, and there are many advantages in comparing single-phase AC, such as power generation, transmission and distribution, and the conversion of electrical energy into mechanical energy.

       As early as1888Russia's Dobrowski invented the three-phase AC system and high efficiencyThree-phase asynchronous motorAt this time, the advantages of AC transmission have been highlighted. But it didn't start with three-phase transmission; in1873In 2000, a Gram DC generator pulled by a gas engine was connected to an electric motor that turned a water pump, using DC power, but the voltage needed to be increased to travel longer distances.

       The appearance of AC induction motor is closely related to the research of "rotating magnetic field".1885A two-phase induction motor was built. in1891When the three-phase AC high-voltage transmission line was put into operation, the total length175KM. Compared with single-phase and two-phaseThree-phase asynchronous motorThe performance, efficiency and material utilization are all better than the first two.

       The use of more phase electricity will make power generation, transmission and distribution and electricity links become complicated, transmission lines increase, generators, transformers, motors and other equipment will tend to be complicated, thus increasing manufacturing costs. SelectThree-phase asynchronous motorThe advantage is to meet the current use, but the cost is more saving, with obvious advantages.
