1. Advantages: (1) resolution of two-phase motor 1. 5 times, to high precision positioning. (2) the stator's main pole number is 6, cross-linking flux is big, and two phase of excitation synthesis efficiency is better than two phase motor torque, torque is higher. 3. Can Y connection or delta, 3 terminals 6 power tube, less than eight two-phase motor power tube. (4) for three phase structure, the relationship between excitation current harmonic is offset, three times smaller than two-phase motor vibration and noise. (5) the cogging torque by two-phase motor 4 harmonics into six harmonic three-phase motor, the cogging torque is smaller than two phase motor. If 2, disadvantages: 12 main pole, for more than two phase motor 8 main pole structure more complicated. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
