Stepper motor

Stepper motor is a kind of electrical pulses into angular displacement of the actuator.Popular point:when the electric motors price stepper driver receives a pulse signal,it is driving a stepper motor according to set the direction of a fixed Angle (and the step Angle).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.Stepping motor in three kinds:permanent magnet (PM),reactive (VR) and hybrid (HB).Permanent magnet stepping is permanent magnet generators for saletwo commonly,torque and volume is small,step Angle is 7.5 or 15 degrees commonly; Reactive stepping generally divided into three,which can realize large torque output,stepper Angle of 1.5 degrees commonly,but the noise and wholesalemotor.blogspot.com vibration are very big.Hybrid stepping refers to a mixture of permanent magnet and the advantages of reactive.It is divided into two and five:two ac electric

motorstep Angle of 1.8 degrees commonly and five stepper Angle of 0.72 degrees.The most

widely used stepper motor.
