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。

introduction：1. Dc motorThere are three ways to speed up：1Is to change the voltage at both ends of the motor，2Its changing the magnetic flux，3It is a string regulating resistor。 2. Changing voltage speed regulation is a common method，Use pulse controlPWMmethod，The input varies with the square wave of different duty cycles，Change the voltage at both ends of the input DC motor armature，Change the DC motor speed，Realize speed control function，It can realize stepless speed regulation，It belongs to constant torque speed regulation。The problem with this speed regulation is that it can generally only be adjusted below the rated speed；Changing flux，Speed regulation by weak magnetic field，It can realize stepless speed regulation，The disadvantage is that it can only be adjusted above the rated speed，Governing timeU、Iinvariability，It belongs to constant power speed regulation；A series regulation resistor is an adjustable resistor in series outside the armature circuitR0，passR0magnify/Reduced change resistanceR+R0To achieve speed co

introduction：Stepper motorIt is an open-loop control motor that converts the electrical pulse signal into angular displacement or linear displacement，It is the main executive element in modern digital program control system，Extremely widely used。。In the case of non-overload，Speed of motor、The position of the stop depends only on the frequency and number of pulses of the pulse signal，It is not affected by changes in load，When the stepper driver receives a pulse signal，It drives the stepper motor to rotate a fixed Angle in the set direction，call“Step Angle”，Its rotation is carried out step by step at a fixed Angle。The amount of angular displacement can be controlled by controlling the number of pulses，So as to achieve the purpose of accurate positioning；At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency，Thus to achieve the purpose of speed regulation。 The reason why the stepper motor vibration is large：Because the stepper motor works in the oscillating region。
