摘要
本文介绍了通过PWM脉冲实现步进电机微步驱动的原理,并给出了一个采用PWM调制方法直接实现步进电机微步驱动的汽车发动机转速表的设计与实现,该设计以软件的算法处理代替了部分相关硬件功能,在保证系统可靠性的前提下有效地降低了仪表成本。
This paper introduces the principle of using PWM to drive stepper motor. The design and implementation of automobile engine speed indicator is given, which uses PWM method to directly realize stepper motor drive in micro-step. This design uses software algorithm to substitute for some functions of the relative hardware. This design effectively reduces the instrument cost, and also guarantees the system reliability.
