introduction：The working principle and function of the relay module are described briefly Relay moduleGenerally made of iron cores、coil、armature、Contact reed and other components。Just apply a voltage to both ends of the coil，A certain amount of current will flow through the coil，This creates an electromagnetic effect，The armature will overcome the tension of the return spring and draw towards the core under the action of electromagnetic force，Thus drive the moving contact and static contact of the armature（Normally open contact）actuation。

introduction：Permanent magnet synchronous motorIt is a synchronous motor that generates a synchronous rotating magnetic field excited by a permanent magnet，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 motor as generator(generator)with；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，Permanent magnet synchronous motor as motor(motor)with。
