What is the difference between step two and three? Commonly used that?
Two phase is two sets of coil, stepper motor basic step Angle is 1.8 ° usually; Three-phase natural is the motor has three sets of coils, there are several kinds of walking distance angles, and the equation is different from the mixture. The phase number of the step motor: the number of coils inside the motor, the two phase, three phases, four phases and five phase stepping motors are commonly used. Step motor phase number is different, it is apart from the different Angle, the general step of the two-phase motor pitch Angle is 0.9 ° / 1.8 ° and 0.75 ° of three-phase / 1.5 ° and 0.36 ° of five phase / 0.72 °.
Two facies in the application of the three-phase stepper motor is the biggest difference to different drive, the market is mainly used in two phase stepping motor, three-phase + three-phase stepper motor drives the overall cost is higher than that of two phase, and the same specifications of the three-phase stepper motor output than two phase is small, but it is generally believed three-phase stability is better, but for using digital stepping driving system, such as Britain, shi EZM digital drive, two phase, three-phase there is no difference in terms of running effect and control precision.
The step of the two phases is 1.8 degrees, and the three-phase step is 1.2 degrees. The three-phase ratio is higher than the two phases, and the two phases are larger than the three phases. Now the most common ones are two-phase stepping motors.
