What is the stepper motor?
Strictly speaking, stepper motor should be an induction motor, its working principle is the use of electronic circuits, the DC voltage into a time-sharing power supply, multi-phase control of current, using this current for stepper motor power supply, step Into the motor to work properly, the drive is for stepper motor time-sharing power supply, multiphase timing controller
Although the stepper motor has been widely used, but the stepper motor does not like the ordinary micro-DC motor, AC motor used in the routine. It must be double ring pulse signal, power drive circuit and other components of the control system can be used. Therefore, it is not easy to make good use of stepper motors. It involves many specialized knowledge of machinery, motors, electronics and computers.
Stepper motor as the implementation of components, is one of the key products of mechanical and electrical integration, widely used in a variety of automated control systems. With the development of microelectronics and computer technology, the demand for stepper motors is increasing day by day, and has applications in various fields of national economy.
Stepper motor is a kind of electric pulse into angular displacement of the implementing agencies. To put it plainly, when the stepper drive receives a pulse signal, it drives the stepping motor to rotate by a fixed angle (ie, step angle) in the set direction. You can control the angular displacement by controlling the number of pulses to achieve the purpose of 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 control.
In modern times, slowly reducer also transplanted to the stepper motor by stepping motor stepper angle with the reducer to subdivide, the precision of the stepper motor is more accurate, so you can do more in the drive Calm, more cost savings, at the same time, the control accuracy can be controlled.
