Effects of coil current phase on eddy current loss of permanent magnets in IPM motors

Abstract

Purpose

Aims to investigate the eddy current loss in permanent magnets of IPM motors.

Design/methodology/approach

Uses the 3D finite element method (3D FEM).

Findings

Finds that the effect of the current phase on the eddy current loss is very different according to the number of slots.

Originality/value

Investigates the eddy current loss in a permanent magnet of an IPM motor.
