Abstract

This contribution discusses the degrees of freedom that could be advantageously exploited in the conception of permanent magnet (PM) machines in the context of very demanding applications, such as electrical vehicle traction. The aim is to inventory degrees of freedom identified in scientific and technical literatures. Identifying these additional degrees of freedom will help positively respond to highly constrained design problems, which are appearing due to the higher usage of electrical energy in many industrial and consumer products. The goal is also to stimulate new ideas in the design of PM synchronous machines.

Summary

Introduction

Due to their attractive features, permanent magnet (PM) synchronous machines are being designed and used in several demanding applications, such as electrical traction Cle [1]; (b) Alstom AGV train [2] In this contribution, techniques helping to improve the performance of PM synchronous machines, from a conceptual point of view, are reviewed. Techniques helping to improve the performance of PM synchronous machines, from a conceptual point of view, are reviewed These techniques help increase the number of degrees of freedom in the design of PM synchronous machines (PMSM). The shift of interesting our societies towards more sustainable uses of energy is an[83,84,85,86], example of contribution proposes to look at the design of permanent magnet synchronous machines this process.
