1. Stepping motor is an open-loop control element stepping motor that converts electric pulse signal into angular displacement or linear displacement.In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step.The 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 motor speed and acceleration can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.
2. Stepper motor is a kind of induction motor, and its working principle is to use electronic circuit to change the direct current into time-sharing power supply, multi-phase timing control current. Only by using this current to power the stepping motor, can the stepping motor work normally.
3, although the stepping motor has been widely used, but the stepping motor is not like the ordinary DC motor, ac motor in the conventional use.It must be composed of double ring pulse signal, power drive circuit and other control system can be used.Therefore, it is not easy to make good use of stepper motor, which involves a lot of professional knowledge such as machinery, motor, electronics and computer.Stepping motor, as an executive component, is one of the key products of mechatronics. It is widely used in various automatic control systems.With the development of microelectronics and computer technology, the demand of stepper motor is increasing day by day, and it has been applied in various fields of national economy.
