Multiple step motor synchronous rotation
This is easy to implement, stepping motor model parameters is the same (best high consistency stepper motor), drive type and set the same parameters, the controller program parameters are the same, suggest that in the same way pulse control multiple drives, multiple drives again (each drive and drive 2 ~ 3 stepper motor). Disadvantages: the pulse voltage must be high, the control current needs to be improved, the drive current must be large, the motor must work under the rated current.

The step motor is an open loop controlling element which converts the electrical pulse signal into angular displacement or line 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. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.
Stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller. Although the stepping motor has been widely used, the step motor is not used as a normal dc motor and ac motor is used regularly. It must be used by the control system such as double ring pulse signal and power drive circuit. Therefore, it is not easy to use a good step motor, which involves a lot of specialized knowledge, such as machinery, electrical machinery, electronics and computers. Stepping motor is one of the key products of mechanical and electrical integration, and is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand for stepping motors is increasing, and there are applications in the national economy.
