And threephase asynchronous machine.
Threephase asynchronous machine is by while accessing 380V three-phase alternating-current supplies（120 degree of phase difference）One class of power supply is electronic
Machine, because copper casting rotor and stator the rotating excitation field rotating speed in the same direction, different of threephase asynchronous machine are into rotation, is present
Revolutional slip, so being threephase asynchronous machine, after the threephase stator winding of motor is passed through three-phase symmetrical alternating current, will produce one
Individual rotating excitation field, rotating excitation field cutting copper casting rotor winding, so as to produce induced-current in copper casting rotor winding（Cast copper turns
Sub- winding is close access）, the copper casting rotor conductor of current-carrying will produce electromagnetic force under the effect of stator rotating excitation field, so that in electricity
Electromagnetic torque, drive motor rotation are formed in machine rotating shaft, and motor direction of rotation is identical with rotating excitation field direction.
The power of three phase alternating current motor is big, predominantly large-size machine, is generally used for the large scale industry with three phase mains and sets
In standby.But in actual application, because the structure between the quality and part of motor key position can turn to the energy of motor
Change efficiency produce influence, and motor produce vibration, noise the problems such as increase loss, reduce the service efficiency of motor.
Therefore, be badly in need of it is a kind of efficiently, become level, a kind of threephase asynchronous machine of multi-speed improves the working environment of workpeople.
