PM Synchronous Motors for Automotive applications: Virtual Prototype and Experimental Testing

International audienceThis study focuses on the design of a permanent magnet (PM) actuator for automotive. The analysis of the specification imposes the need for a powerful motor in a small volume. Following this, a first finiteelement model (FEM) of the motor was developed using amethodology defined by the authors. A second numerical model was also developed using the MATLAB software. It represents a "virtual prototype" that enables to simulate, for different driving cycles and for different applications, the drive (motor+inverter) coupled to a mechanical load. This model takes into account the motor control too. The FE model has been validated by the realization and the tests of real a prototype
