Based on the principle of torque generation, the stepper motor can be divided into reactive, permanent magnet, and hybrid stepper motor. I will take the reactive stepper motor as an example to illustrate the structure and working principle. 1, The Basic Structure of Stepper Motor The basic structure

　　The brushed DC Motor has the advantage of speed control and start-up characteristic, high stall torque. However, because of the mechanical commutation of brush and commutator, it affects the life span, performance, and reliability of the motor, and the associated fire will also interfere with othe

When DC Motor is in operation, a spark is easily generated between brush and commutator, which is harmful for the operation of the motor. When the spark level is too high, it will burn out the motor.when the range of spark on the brush is very small, it has very little effect on the operation of

　　The Stepper motor is a typical mechatronic component. Compared with an ordinary DC motor, its internal structure and control principle is more complex. It can be divided into a hybrid(HB type), permanent magnet(PM type), and reactive(VR type). the structure of the HB type has some characteristics

　　For the position closed-loop control, although it can improve the precision of position and output torque in the application, yet the specific performance is direct to the drive technology and its characteristic.　　In practice, the controller will send directions and pulse signals. After sending th

　　In Application, the stepper motor can’t directly connect AC power and DC power, it should be equipped with A driver. In an open-loop control system, it can realize the diagonal displacement after receiving the control pulse.　　At the same time, it can be used as the servo control system, if the obj
