The number of phases of the "driver stepper motor" of computer embroidery machine accessories refers to the number of coil groups inside the motor. Currently, two-phase, three-phase, four-phase, and five-phase stepper motors are commonly used. Different motor phases have different step angles. Generally, the step angle of two-phase motors is 0.9 ° / 1.8 °, three-phase motors are 0.75 ° / 1.5 °, etc., and five-phase motors are 0.36 ° / 0.72 °. When there is no subdivision driver, users mainly rely on the selection of stepper motors with different phase numbers to meet their own step angle requirements. If a subdivision driver is used, the “phase number” will become meaningless. The user only needs to change the subdivision number on the driver to change the step angle.
Different in structure and materials, reactive motors do not have permanent magnetic materials inside like hybrid motors, so reactive motors have no self-resistance, while hybrid motors have self-resistance (ie, there is a certain Self-locking force). ? There is a difference in operating performance. The hybrid motor operates relatively smoothly, the output torque is relatively large, and the operating sound is low. There is a difference in price between the two motors. The reactive motor is relatively cheaper than the hybrid motor.
