DESIGN OF AN AXIAL FLUX BRUSHLESS DC MOTOR

Abstract

This paper describes a design methodology of an axial flux Brushless DC motor modular structure with concentrated winding, reducing the energy consumption of electric vehicles as well as their cost. This methodology rests on the development of an analytical dimensioning model of the motor - converter taking in account of several technological, physical constraints related to the global system. This model is validated as well as completed by finite elements simulations. The coupling of this model to the power train losses model and the motor mass model pose an optimization problem of the consumption and the cost of electrics vehicles. This problem is solved by the software optimization based on the Genetic Algorithms method described in [1].
