Abstract
In a drive system, including a stator and a rotor associated with an energy transmission system supplying energy to a load on the rotor, 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.

An electrical drive machine associated with a power transmission system, comprising:
- a drive system, including a stator and a rotor having a rotor winding, associated with the power transmission system that supplies electrical power to a load on the rotor, where a drive function and a power transmission function are largely independent of one another and a subharmonic air-gap field component is used to transmit the electrical power to the rotor winding.
