摘要

提出了一种具有八极、90个转子齿和施加外几何形状的小型两相混合式步进电机的优化设计方法。对转子永磁体尺寸、齿槽宽度比、转子两部分间隙进行修正，分析其对电机保持转矩和制动转矩的影响。提出了提高扭矩密度或减小制动力矩的解决方案。

Optimization of a High Torque Density Small Hybrid Stepper using 3D FEM Model

The paper presents an optimization of a small two-phase hybrid stepper with eight poles, 90 rotor teeth, and imposed outer geometry. The rotor permanent magnet dimensions, the tooth/slot width ratio, as well as the gap between the two rotor parts were modified to analyze their influence upon motor holding torque and detent torque. Solutions for obtaining a higher torque density or a smaller detent torque are proposed.
