introduction：The water-cooled permanent magnet synchronous motor is a synchronous motor which is excited by a permanent magnet and generates a synchronous rotating magnetic field，The permanent magnet acts as a rotor to generate a rotating magnetic field，Three-phase stator winding reacts through armature under the action of rotating magnetic field，Induced three-phase symmetrical current。 At this time the kinetic energy of the rotor is converted into electrical energy，Permanent magnet synchronous motorFor generator；In addition，When the stator side passes a three-phase symmetrical current，Because the three phase stator is different in space position120，So the three-phase stator current creates a rotating magnetic field in space，The rotor is moved by the electromagnetic force in the rotating magnetic field，This converts electrical energy into kinetic energy，Water cooled permanent magnet synchronous motor is used as motor。

introduction：one、Three-phase asynchronous motorRotation principle of： The prerequisite for a three-phase asynchronous motor to rotate is to have a rotating magnetic field，The stator winding of three-phase asynchronous motor is used to generate rotating magnetic field。We know，However, the voltage between the phase and the phase of the phase supply is different in phase120metric，The three windings in the stator of the three-phase asynchronous motor are also different in spatial orientation120The degree of，In this way，When a three-phase power supply is fed into the stator winding，The stator winding creates a rotating magnetic field，The process of its production is shown in the figure1As indicated。The figure is divided into four moments to describe the process of generating the rotating magnetic field。The current changes every period，The rotating magnetic field rotates once in space，That is, the rotation speed of the rotating magnetic field is synchronized with the change of the current。The rotation speed of the rotating
