Three-phase asynchronous motor is how to turn up?

After the three-phase alternating current flow into the three-phase stator winding,the stator cavity to produce a rotating magnetic field.Stationary before rotating the rotor conductors under the effect of rotating magnetic field,the equivalent of the rotor conductors relative to cut magnetic lines,which produced the induced current in the rotor conductors (electromagnetic wholesalemotor.blogspot.com induction principle).These just son of induced current in the conductor will electric motors price happen in production field movement (current effect of electromagnetic force).Due to the rotor inner conductor is always symmetrical layout,the electromagnetic force on the conductor produces the reverse direction,so as to form the electromagnetic torque,the rotor rotation.Due to the mini electric motor current in the rotor conductors are the stator rotating magnetic field induction,therefore also calls the induction motor.And as a result of the rotor speed is always lower than the speed of the stator rotating magnetic field,so is gasoline generator also known as asynchronous motor.
