Low weight and high power density is a main focus in electro mobility. The most common traction motors for vehicle applications are synchronous motors or induction motors whereas synchronous motors are preferred because of their advantage regarding power density and weight. But each of the motor concepts has its advantages and disadvantages. In this paper it is shown that Siemens has managed to increase the power density of induction motors and simultaneously reduced the main disadvantage of the induction motor by optimizing some parts of the motor. With this adaption it is possible to reduce the weight and as a result of this defining parameter the induction motor has in summary more advantages compared with the synchronous motor. Therefore it can be the better choice for electro mobility.
