Abstract
The machine includes a rotor with an inner rotor core and an outer rotor core and a double-sided stator with an inner stator side and an outer stator side. The double-sided stator is concentrically disposed between the inner rotor core and the outer rotor core of the wind turbine generator. The double-sided stator is configured to enable at least a portion of magnetic flux to be shared between the inner stator side and the outer stator side. An example of a particularly useful embodiment for the machine includes a ship propulsion motor.
