Zusammenfassung:A new method to calculate the permanent magnet synchronous motor (PMSM) temperature rising in electric vehicle (EV) was proposed based on the stator resistance identification. The measure theory of the motor temperature rising with the stator resistance was discussed at firstly. A PMSM dynamic math model was built which was the research object. Then the resistance identification system model was built on the model reference adaptive system (MRAS) theory. The simulation diagram of the mutual MRAS model was constructed and the resistance identification performance was studied in different motor states.Simulation results indicate that the stator resistance identification model with the MRAS was effective.At the same time, the identification of motor temperature rising was possible with the identification of the stator resistance identification.
