Multiphase

The traction drives currently being used in hybrid and electric vehicles are predominantly three-phase motors (synchronous or asynchronous motors). However, there are various reasons why it can make good sense to equip these drive units with an even higher number of phases (e.g. five or six phases). Several applications are already making use of such motors. This project is investigating, selecting and improving such “multiphase drives" especially in respect of their suitability for use in electromobility, since the drives of electric vehicles must take account of several requirements which have so far not been described in sufficient detail in the literature.
