摘 要: 目前,电机控制是自动控制领域中极其重要的组成部分。步进电机是一种数字控制电机,它将脉冲信号转变成角位移,电机的转速由脉冲信号频率决定。该文介绍了一种简单的步进电机控制芯片LMD18245,利用它可以自行设计步进电机的驱动模块,从而为系统设计降低成本。 At present, the control of motor is an important part in auto control field. Stepper motor is a motor controlled by digital signal, which converts pulse signal into angle displacement. The wheeling speed is controlled by the frequency of pulse signal. This paper introduces a simple stepper motor control chip LMD18245. By using it, we can design the drive module of stepper motor by ourselves, and thereby decrease the cost of system design.
