| 中文摘要: |
| 磁路计算是电机设计中重要的教学内容,本文通过对磁路计算基本原理的论述引出了将物理概念转化为几何关系的思想,以计算极弧系数的确定、凸极同步机气隙形状的确定、气隙系数的确定为例阐述了这种思想。在教学中通过传递这种思想,不仅可以提高学生对磁路计算的理解,而且为学生今后在学习、工作中解决类似问题提供了一种思维方法。 |
| 英文摘要: |
| Magnetic circuit calculation is an important teaching content in the course of Electric machine design. In this paper, the idea of transforming physical concepts into geometric relations is introduced by discussing the basic principles used in magnetic circuit calculation. The idea is elaborated from the determination of calculation pole arc coefficient, air gap shape of salient pole synchronous machine and air gap coefficient. As this idea is passed in the teaching process, which can not only improve students’understanding of magnetic circuit calculation, but also provide a way of thinking for students to solve similar problems in their future study and work. |
