Modélisation par éléments finis, validation expérimentale et optimisation d'une machine synchrone à aimants permanents

Abstract

During this master’s degree at the École de Technologie Supérieure in Montréal, the present work examines modeling by finite elements of a permanent magnet synchronous motor The first objective was to develop the electric motor’s model into the Maxwell software while considering the winding’s characteristics, the materials and the pieces’ geometry. As a second step, the magnet's materials and magnetization profile was determined to obtain a trapeze-shaped back electromotive force. A sample from a ferromagnetic material was tested in a thermal chamber and used to quantify iron loss as a function of electric frequency and temperature. Additionally, a thermal model outlining the magnets' behavior was implemented to increase the accuracy of the motor's model. Finally, the motor's model was validated on a work bench according to experimental measures. Since Procycle enterprise's main objective is to reduce the motor's mass as well as optimizing its electromechanical performance, a sensitivity analysis was conducted. Thus, performance improvements were assessed by changing different variables such as materials, stator’s geometry, and windings.
