This paper deals with an algorithm to optimize the efficiency of induction motors used in electrified powertrains of battery electric or hybrid vehicles. In this drivetrain concepts it is necessary to design electric drives of high efficiency in order to maximize driving range and performance. The algorithm is part of a holistic design process which is presented as well. It will be shown how efficiency maps are generated and created and in which way different control strategies influence the drive efficiency. Therefore efficiency analyses of two different induction machines with field oriented and rotor frequency control is presented and compared.
