1. What is a stepper motor? Stepper motor is an electrical pulse into the angular displacement of the implementing agency. Popular little lesson: When the driver receives a step pulse signal,alphabet embroidery designs (http://www.eagledigitizing.com/), it will drive a stepper motor to set the direction of rotation at a fixed angle (and the step angle). You can control the number of pulses to control the angular displacement, so as to achieve accurate positioning purposes; the same time you can control the pulse frequency to control the motor rotation speed and acceleration,embroidery digitizers (http://www.eagledigitizing.com/), to achieve speed control purposes. 2. What kinds of stepper motor points? In three stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB) permanent magnet stepper usually two-phase, torque and volume than the small, step angle is generally 15 degrees or 7.5 degrees; reaction step is generally three-phase,embroidery design (http://www.eagledigitizing.com/), high torque output can be achieved, step angle of 1.5 degrees is generally,embroidery designs digitizing (http://www.eagledigitizing.com/), but the noise and vibration are large. 80 countries in Europe and America have been eliminated; hybrid stepper is a mix of permanent magnet and reactive advantages.
