The principle of stepper motor, 2 phase, 5 phase is what meaning, where information?
Hybrid stepping is the advantage of mixing permanent magnet and reaction. It is divided into two phases and five phases: two phase stepping angle is generally 1.8 degrees, while the five phase stepping angle is generally 0.72 degrees. This stepper motor is most widely used.
There are three kinds of stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB).Permanent magnet stepping is generally two-phase, torque and volume of smaller, step angle is generally 7.5 degrees or 15 degrees;The reaction step is generally three-phase, and can achieve large torque output. The step angle is generally 1.5 degrees, but the noise and vibration are very large. In Europe and the United States and other developed countries, in 80s has been eliminated;
Stepping motor is a kind of actuator that transforms electric pulse into angular displacement. Generally speaking, when the stepping driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (and step angle) in the set direction. Number of pulses can be controlled by controlling the angular displacement, so as to achieve 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.
