Three-Phase PMSM Drive with Thermal Model

This example shows a Permanent Magnet Synchronous Machine (PMSM) and an inverter sized for use in a typical hybrid vehicle. The PMSM includes a thermal model and empirical iron losses. The inverter is connected directly to the vehicle battery, but you can also implement a DC-DC converter stage in between. You can use this model to design the PMSM controller, by selecting the architecture and the gains to achieve the desired performance. The initial temperature of the stator windings and rotor is set to 25 degrees Celsius. Ambient temperature is 27 degrees Celsius. The Scopes subsystem contains scopes that allow you to see the simulation results.
