Stepper motor is the industry professionals to "motor" another name, a stepping motor is the electric pulse signal into an angular displacement or line Shen force stepper motor, stepper motor driver
The displacement components of the open-loop control. In the overload situation, the rotational speed of the motor, stop position depends only on the pulse frequency and pulse number, regardless of load changes, that is to add a pulse motor, the motor is turned to a step angle. The existence of this linear relationship, the stepper motor with only periodic error without accumulated error and so on. Makes the speed, position in the control field with stepper motor to control becomes very simple.
Stepper motor is a kind of induction motor, its working principle is to use the electronic circuit, the DC component power supply, multiphase sequence control current, the current power supply for stepper motor, stepper motor can work normally, the drive for stepping motor of time-sharing power supply, multiphase sequence controller.
Although the stepper motor has been widely used, but the stepper motor is not as common DC motor, AC motor used in conventional. It must be double-ring pulse signal, power drive control system composed of the circuit can be used. So use the stepper motor is not easy, it relates to the machinery, motors, electronic and computer expertise.
Stepper motor is a kind of electrical pulses into angular displacement actuator. Popular point stresses: when stepping driver receives a pulse signal, it drives stepper motor rotate in the direction set by a fixed point of view ( and the stepping angle ). You can control the number of pulses to control the angular displacement, thus achieving the purpose of accurate positioning; at the same time, you can control the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.
