步进电动机细分精度自动补偿的研究

Auto-Compensation of Subdivision Precision of Stepper Motors

为了减少工作时的振动和提高分辨率,步进电动机通常工作在细分运行状态。而步矩角的细分精度是细分运行的主要指标之一。首先讨论了混合式步进电动机细分运行时误差的产生原因,然后给出了对细分精度的自动补偿办法和补偿结果。

In order to reduce the vibration and improve the resolution, the stepper motor usually operates in the subdi- vision mode, and the homogeneity of the subdivision is one of the main factors considered. The cause of the error in the op- eration of the hybrid stepper motor was discussed, and the method and result of auto-compensation of the subdivision preci- sion were given.
