Abstract
A method and assembly of a dry cavity oil cooled electric machine includes a housing, a shaft configured to operably couple with a source of rotational force and rotate about a rotational axis, and an exciter rotor and a permanent magnet generator rotor carried by the shaft, wherein the exciter rotor and the permanent magnet generator rotor rotate relative to the housing, which provides such a construction of dry cavity generators that have high efficiency and high power density.
