Overview

As a method for analyzing the electromagnetic vibration of the motor, there is a harmonic analysis of the electromagnetic force of the tooth to evaluate the spatial distribution of the electromagnetic force for each order (Fig. a).
This document describes the procedure to confirm the spatial modes of the electromagnetic force acting on a stator using a radar graph from electromagnetic force analysis results obtained with JMAG.
