What is the difference between a two-phase stepping motor and a four-phase stepping motor? The two-phase stepping motor has only two windings on the stator and four outgoing wires. The whole step is 1. 8 °, Half step is 0. 9 °. In the driver, it is only necessary to control the current on-off and current direction of the two-phase winding. The four-phase stepping motor has four windings on the stator, eight outgoing wires, and the whole step is 0. 9 °, Half step is 0. 45 ° However, the four windings need to be controlled in the driver, and the circuit is relatively complicated. Therefore, the two-phase motor is equipped with a two-phase driver, and the Four-Phase Eight-wire motor has three connection methods: parallel connection, series connection and unipolar connection. Parallel connection: the four-phase winding is two-phase, the resistance and inductance of the winding are doubled, the acceleration performance of the motor is good, and the high-speed load torque is large, but the motor needs to input a current twice the rated current, the heating is relatively large, and the requirement on the output capability of the driver is correspondingly increased. However, when used in series, the resistance and inductance of the winding increase exponentially, the motor is stable at low speed, with less noise and heat, low requirements on the driver, but high speed torque loss. Therefore, users can choose the four-phase and eight-wire stepping motor wiring method according to requirements.
