Step 2: what does the 5 phase mean
Stepping motor is an actuator that converts electrical impulses into angular displacement. Popular point: when the 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). It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency.
There are three types of stepper motors: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 15 degrees.
The reaction type step is generally three-phase, can realize the big torque output, the step Angle usually is 1.5 degrees, but the noise and vibration are very large. Developed countries such as the United States and Europe were eliminated in the 1980s. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phases and five phases: the Angle of two phases is 1.8 degrees, and the fifth phase Angle is 0.72 degrees. This step is the most widely used.
