High efficiency, high power levels, reliability are demands that have led many researchers to dive into the field of multiphase motors. Especially the world of the electric car, a growing trend, is pushing for increasingly high-performance solutions that will facilitate their widespread use. The purpose of this work is to provide an overview of the multi-phase permanent magnet synchronous motor and to show what steps are needed to calculate the basic parameters to highlight some of the benefits. In order to understand how a permanent-magnet motor works, a review of three-phase motors is presented, specifying transformations that allow simplified modeling to control them.
