Introduction to stepping motor

Stepping motor is a kind of induction motor. Its working principle is to use electronic circuit to change the DC current into power supply. The current is controlled by multi-phase sequence. Only when this current is used to supply power to the stepping motor can the stepping motor work normally. The driver is a multi-phase sequence controller that supplies power to the stepping motor in time. Although stepping motor has been widely used, stepping motor can not be used like ordinary DC motor, and AC motor is used under normal conditions. It can only be used if the control system is composed of double ring pulse signal, power drive circuit, etc. Therefore, it is not easy to use stepping motor well, which involves many professional knowledge such as machinery, motor, electronics and computer.

As an executive component, stepping motor is one of the key products of mechatronics, which is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand for stepper motors is increasing day by day, which has been applied in various areas of the national economy.

Stepper motor is an actuator that converts electrical pulse into angular displacement. More generally, when the stepping driver receives a pulse signal, it will drive the stepping motor to rotate a fixed angle (i.e. step angle) in the set direction. You can control the angular displacement by controlling the number of pulses to achieve accurate positioning; At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency, so as to achieve the purpose of speed regulation.
