In the running process of the stepper motor, it will produce noise and vibration. For these problems, what methods can we take advantage of to eliminate?　　1. Avoiding the resonance zone　　With the same as the synchronous motor and mechanical system, there exists natural vibration frequency. It is i

　　With the rapid development of electronic technology, the performance index of frequency control of motor speed can reach up to or even exceed the system of DC motor speed regulation. By adjusting the pulse frequency of the input driver and subdivision parameter, the speed of the stepper motor can

　　The stepper motor is a miniature motor used for precise positioning, which equips with a drive circuit.　　The stepper motor is called a pulse motor, an actuator that is controlled by an electric pulse signal and coverts an electric pulse signal into angular displacement or linear displacement. When

　　The application of stepper motor in production and life is very common, and the generation of all-digital AC servo motor makes it more and more important in the digital control research, so the comparison between the stepper motor and AC servo motor is very meaningful.　　Performance of Comparative

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
