Abstract :
High performance for electric vehicle drives is obtained by allowing the machine to carry a load exceeding its rated values for short periods of time. The limit of such overloading is set by the maximum temperature rise and broken bars in the motor. In this case it is essential to predict the behavior of the machine. The transient coupled computation of the magnetic and thermal field of an induction motor for a vehicle application is discussed in this paper. Theoretical approach together with experimental results derived from a 380 V 50 Hz two-pole 1.1 kW squirrel-cage induction motor confirms the validity of the proposed method
