PM synchronous motors for automotive applications: Virtual prototype and experimental testing

This 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 finite-element model (FEM) of the motor was developed using a methodology 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.
