摘要
本文运用有限元方法分析一台800W稀土永磁同步电动机内部电磁场的分布情况,并在传统的计算电枢反应电抗的基础上提出了一种基于电势平衡方程式的计算方法,本文称之为"电势法"。文章还运用直接负载法测定出样机在不同负载下的同步电抗参数,验证了"电势法"的正确性。
The paper analyses the distribution of magnetic field in the permanent magnet synchronous motor with rated power of 800W. On the basis of the traditional approach to calculating armature reactance, we put forward a new method which is based on the calculation of the electromotive\|force equation, and name it after 'electromotive\|force method'. Moreover, we determine the reactances of the experimental motor by the way of direct\|load method, and verify the validity of 'electromotive\|force method'.
