Abstract
The application of software for the design of electrical equipment has been increasingly used to improve its efficiency. In the project of electric motors the definition of the design of the stator slots is an extremely important feature, since the stator windings are accommodated in this place and for this reason there is a large concentration of electric field. The electric field intensity is usually associated with the presence of faults and must therefore be investigated. Through the Finite Element Method (FEM) it is possible to simulate electric field on surfaces and different geometries. In this paper, an evaluation of electric field will be presented through the variations of design of the stator slots of a Permanent-Magnet Synchronous Machine (PMSM) to evaluate the most efficient profile for this application.
