Optimization and design for a radial flux permanent magnet motor for electric vehicle

الملخص EN

This paper deals with the design and the optimization of permanent magnet motors.

Five trapezoidal and four sinusoidal wave-form motor configurations were investigated and analyzed.

Firstly, an analytic sizing was led along with an electromagnetic modeling by finite element method.

Secondly, a finer modeling with finite element was realized dynamically.

The optimization of the traction motor cost under constraints by the genetic algorithms method has allowed choosing a motor with sinusoidal wave-form, five pole pairs and twelve slots.

This motor belongs to the second configuration with sinusoidal wave-form.
