Three-phase asynchronous motorIt is a device that converts electrical energy into mechanical energy; When the stator winding passes through the three-phase current, the rotating magnetic field will be generated in the rotor winding, the induced electromotive force will be generated in the rotor winding of the closed loop, the rotor current and the magnetic field will interact to produce electromagnetic torque, so that the rotor drives the mechanical load to rotate.

         120°The electrical Angle. The coils in the phase group should be in positive series, that is, the "head" and the "tail" are connected inLow-power three-phase asynchronous motorThe coils in a polar phase group are usually wound continuously and do not require a joint.

       The connection in the phase winding, which belongs to the same phase and the same branch of each pole phase group, usually adopts the positive series connection and the reverse series connection;Three-phase asynchronous motorThe reason it is called "asynchronous" is because the phase of the three-phase winding is separated from each other in the distribution of space120°The electrical Angle, on this premise, is usually the interval between the lead lines of the three-phase winding120°Electrical point of view, this is mainly because in our production process, from the process considerations always hope that all the lead lines are close to the outlet hole in the frame.
