Design and Investigation of Axial Flux Permanent Magnet Synchronous Machine for electric vehicles

Vehicle emissions explosively increase in the number of vehicles. Therefore, it is essential to find a solution to reduce (or eliminate) pollution of the environment. When public transport (trains, buses and trams) offer ecological (electric) solutions for private transport, the electrification of vehicles is one of the solutions proposed by car manufacturers. Studies show that most of the pollution in urban areas are due to this matter. The Axial Flux and Permanent Magnet Machine (MFAP) represent a serious issue for electric traction because of its high density and mass density of torque. In this article we have designed the permanent flux permanent machine FLP (AFPM), without the TORN NS topology. The purpose of the research is to determine the flow density of the model, especially gaps through a numerical method. Analysis of the slotless machine (AFPM) using the finite element method (FEM). The form of the machine was implemented on the commercial code Maxwell 16.0. The result obtained is illustrated and in the paper and numerical quality is relatively good agreement with those of literature.

I. Introduction

Drives have been progressively working for more than a century in every areas of society (in developed countries they consume about a quarter of total electricity consumption and over 70% of consumption industrial [1] ). In most cases, the load is driven via a more or less complex mechanical transmission: gearbox, multiplier, rack pinion, differential, universal joints … The transmission then has the role of adapting the load to the engine, which allows to use, more often than not, standard motors.
