Inductance Characteristics of 3-Phase Flux-Switching Permanent Magnet Machine With Doubly-Salient Structure
摘要
Abstract
In this paper, the inductance characteristics of a novel 3-phase 12/10 pole (12-stator- tooth/10-rotor-pole) flux-switching permanent magnet (FSPM) machine with doubly-salient structure is investigated based on finite element (FE) analysis. Firstly, the topology and operation principle of the machine are presented. Secondly, the apparent (static) and incremental (dynamic) inductances are defined. Then, the conventional calculation method of transforming the 3-phase inductances in stator frame into dq-axes rotor frame is performed, which consumes lots of time. To avoid it, a newly simplified and fast method is proposed to obtain the d-axis and q-axis inductances directly and accurately at only two special rotor positions. The proposed method is validated by the comparison of the predicted results in two ways. The experimental measurement verifies the predicted results.关键词
