步进电动机升降速曲线的设计

The Design of the Rise and Fall-speed Curve of Stepper Motor

为了保证步进电动机不丢步,必须使步进电动机的输出力矩大于负载转矩,同时要保证步进脉冲一定的宽度,因此选择合理的升降速曲线十分重要。针对这个问题,介绍了三种不同的步进电动机升降速曲线设计方法,并根据不同的设计方法对步进电动机的升降速过程进行处理。

In order to insure that no step to.lose, the torque of the output must be big than the torque of the load and there are some requirements to ensure certain width of the stepping pulse. So it＇s important to choose the reasonable speed - curve, Aiming at the problem, three different methods of the designs of the rise and fall - speed curve and the different disposals according to different methods ore introduced.
