introduction：Stepper motorThe operation state is different from that of ordinary motors，It turns step by step with the pulse of the power supply，Its a digital motor。The stepper motor rotates the corresponding number of steps with the number of power pulses supplied，And the Angle of each step is fixed，So the stepper motor is controlled by the number of turns required、Angle，Widely used in CNC machine tools、Automation equipment、Instrumentation and other industries。This section describes the widely used reactive stepping motor。 The reactive stepper motor works by generating torque according to the reluctance property，It follows the principle that the magnetic flux always closes along a path with low magnetoresistance，Torque is formed by magnetic pull。The switched reluctance motor described earlier can also be regarded as stepping operation，Because the rotor rotates at a certain Angle when each group of coil power is switched，Just stop switching and the rotor stops moving，Except the Angle of each step is30The degree of，T

introduction：Dc motor（direct current machine）It is able to convert direct current energy into mechanical energy（Direct current motor）Or convert mechanical energy into direct current energy（Dc generator）Rotary motor。It is a motor that can convert direct current energy and mechanical energy into each other。It is a DC motor when it is operated as a motor，Convert electrical energy into mechanical energy；It is a DC generator when operating as a generator，Convert mechanical energy into electrical energy。 Working principle： A annular permanent magnet is fixed inside the DC motor，The current passes through a coil on the rotor to generate an amperage force，When the coil on the rotor is parallel to the magnetic field，If we continue to turn, the direction of the magnetic field will change，Therefore, the brush at the end of the rotor is in alternating contact with the transfer sheet，This changes the direction of the current in the coil，The direction of the resulting Lorentz force remains the same，So the motor can keep moving in

introduction：Stepper motor 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。 Stepper motor is a kind of induction motor，It works by using electronic circui
