基于Ansoft的爪极发电机空载漏磁分析

Analysis on No-load Leakage Magnetic of a Claw-pole Generator Based on Ansoft

针对漏磁影响爪极发电机效率问题,利用Ansoft软件的Rxmprt和Maxwell 3D模块,建立了一台爪极发电机的三维有限元瞬态仿真模型。通过在模型中添加漏磁分析辅助面的方法,分析了电机漏磁分布的规律。在空载、恒定励磁条件下,分析了电机漏磁随转速变化的规律。

A three dimensional （ 3 D） finite element model of a claw pole generator was presented using Rmxprt and Maxwell 3D of Ansoft. The distribution rules of leakage flux were analyzed by adding adjective faces in the 3 D finite element model. The rules between the leakage flux and rotation speeds were analyzed on status with no-load and invariable excitation.
