Stepper motor is a kind of electrical pulses into angular displacement of the actuator. When the stepper motor driver receives a pulse signal, it drives stepper motor according to set the direction of a fixed point (Called 'step Angle'), its rotation is based on the Angle of the fixed step by step. Can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating. Stepper motor can be as a control with special motor, using its no accumulated error (Accuracy of 100%)Characteristics, widely used in all kinds of open loop control. Now more commonly used stepping motor including reactive stepper motor (VR）, permanent magnet stepper motor (PM), hybrid stepping motor (HB）And single-phase stepper motor, etc. General for two phase permanent magnet stepper motor, torque and volume is small, step Angle is commonly 7. 5 or 15 degrees; General for three-phase reactive stepper motor, which can realize large torque output, stepper Angle generally to 1. 5 degrees, but the noise and vibration are very big. Reactive stepping motor rotor magnetic circuit made of soft magnetic materials, multiphase field winding of the stator, the torque caused by the change of permeability. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
