摘要
介绍瑞士Switec公司M-S型汽车仪表机心步进电机的内部结构、工作原理和控制方法。利用单片机产生控制脉冲信号,分配成一定相序来控制步进电机各相通断,实现步进电机微步距运行的PWM驱动。
The author introduces the structure, working principle and control method of the M-S stepping motor for instrumental module made by Switec company in Swiss. Control pulses produced by the SCM are assigned to a phase order to control the on-off of the phases in the stepping motor, which realizes the PWM driving for its microstep running.
