ELECTRIC DRIVE MACHINE

摘要

The invention relates to an electric drive machine (1) comprising a stator (2) and a rotor (3) forming a drive system. The drive system is associated with an energy transmission system (5) for supplying electric energy to a load on the rotor, wherein the drive function and the energy transmission function are largely independent of each other. A subharmonic air gap field portion is used for transmitting electric energy to a rotor winding (5).
