步进电动机是一种可以将脉冲指令转换为角位移或转速的控制电机,由于其机械角位移与脉冲量严格成正比,又具有定位精度高,同步运行特性好的特点,作为小功率伺服系统中的执行元件较为理想.近年来.随着电子工业的发展,步进电动机的控制单元逐步集成化,使得系统设计更加方便、可靠,从而进一步扩大了此类电机在机械工业、航空工业、航天工业和仪器仪表领域中的应用范围.本文略谈步进电动机用于稳速系统、定位系统、随动系统等伺服系统的几点体会.
Stepping motor is a kind of control motor that can convert pulse command to angular displacement or rotation speed. Because its mechanical angular displacement is strictly proportional to the pulse quantity, it has the characteristics of high positioning accuracy and good synchronous operation. As a low power servo system In recent years, with the development of electronic industry, stepper motor control unit gradually integrated, making system design more convenient and reliable, thus further expanding the type of motor in the machinery industry, aviation industry, aerospace Industrial and instrumentation in the field of application.This article briefly on the stepping motor used in steady-speed systems, positioning systems, servo system servo system experience.
