Abstract
This document describes the stresses in the bridges of three types of interior permanent magnet (IPM) machines. These are machines which had a V-magnet slot, machines which have a straight slot, in machines which have a V configuration with a center post. Formulae for calculating the bridge stresses are included for the straight and V shaped slots. The formulae are determined from a mathematical model statistically based on finite element models.
