摘要

摘要: 用于水下航行体推进装置的功率型无铁芯永磁盘式(AFPM)电机定子绕组由于直接暴露在交变磁场中, 会产生很大的涡流损耗, 从而影响电机性能。本文推导了2种截面导体在交变磁场中的涡流损耗计算公式, 提出了使用股间绝缘细绞合线代替原有扁平矩形导线来减少涡流损耗, 建立了等效直线电机2D有限元模型, 分析计算了绕组涡流损耗, 同时通过11 kW原理样机损耗试验, 验证了相关理论与计算方法的可行性和准确性。

Abstract: The power-type axial flux permanent magnet(AFPM) brushless machine without stator cores is used for pro-pelling device of underwater vehicle. However, high eddy current loss is induced in its stator windings because the windings are directly exposed to the time-varying air gap magnetic field, which influences the performance of the ma-chine. In this paper, the eddy current loss calculating formulas for two winding conductor sizes are deduced, and a solu-tion to reduce the eddy current loss in coreless-stator windings is proposed by substituting thin inter-twist wire for the flat conductor with rectangular cross-section. A two-dimensional finite element model of equivalent linear motor is con-structed to analyze and calculate the eddy current loss. Eddy current test of a 11 kW AFPM machine with coreless-stator verifies the validity and feasibility of the proposed theory and method．
