This paper investigates the impact of downsizing induction motors for battery-electrical-vehicles (BEV). With three electrical torque equations based on stator current, stator voltage and stator flux density, we display the overload potential of an induction motor. The traditional efficiency map of an induction motor is extended by a so-called overload-Area. An algorithm for sizing an induction motor generates a set of input variables which will be forwarded to a driving cycle simulation. As a result of downsizing, the motor will be actuated more often in the overload-Area and in more efficient regimes, leading to a significant reduction of energy consumption.     «
