The transient coupled computation of the magnetic and thermal fleld of a permanent magnet excited synchronous motor for a vehicle application is discussed. The coupling of the magnetic and dual thermal models is accomplished through a detailed loss calculation and the temperature dependence of the permanent magnets and conductive materials. Both fields are calculated by means of the FEM method on independent meshes. In order to avoid numerical problems, the field and loss calculations are performed on different time scales. The simulation methods are applied to a six-pole 45 kW PMSM machine for different working conditions. The results are compared with measurements.
