基于有限元法的直流串励变桨电动机设计

Design of DC Series Pitch-controlled Motor Based on Finite Element Method

针对直流串励变桨电动机要求体积小、重量轻和过载能力强的特点,合理设计电机结构并较为准确地计算气隙磁场的大小尤其关键。该文采用有限元方法代替传统磁路方法计算,并利用实例进行分析直流串励电动机的气隙磁场。

In allied to the characteristics of DC series pitch-controlled motor that is small-bulk,light-weight and strong-overload ability,it is especially critical to design the motor construction reasonably,and calculate the magnitude of air-gap field relative exactly.This thesis calculated with finite element method instead of traditional magnetic circuit method,and exemplified the gap-air field of DC series pitch-controlled motor.
