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.
