This section covers all types of motors, from the elementary circuitry needed to control a variable reluctance motor, to the H-bridge circuitry needed to control a bipolar permanent magnet motor.
The bipolar two-phase hybrid stepping motor integrated with chip L6217A was mainly used in this drive circuit to realize the ability of current subdivision.
该驱动电路主要应用双极性两相混合式步进电机驱动集成芯片L 6217a，来实现电流细分功能。
