步进电机原理及使用说明------外文翻译.doc

Step-by-step electric motor is the ring opening gating element changing electricity pulse signal into angular displacement or line displacement. Under the situation of must overload, the electric motor rotation rate , discontinuous location depend on pulse signal frequency and pulse number only , make free from being loaded with the effect changing but, be to add a pulse signal for electric motor, the electric motor had rotated a step spur angle then. This gleam of the sexual relationships existence, adds step-by-step electric motor characteristics such as only having the cyclicity error but there being no accumulative error. Feasible simplicity controlling a field using step-by-step electric motor to come to control changeable extraordinary in speed, location etc.



步进电机是将电脉冲信号转变为角位移或线位移的开环控制元件。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，即给电机加一个脉冲信号，电机则转过一个步距角。这一线性关系的存在，加上步进电机只有周期性的误差而无累积误差等特点。使得在速度、位置等控制领域用步进电机来控制变的非常的简单。
