ROTOR ASSEMBLY FOR AN ELECTRIC MACHINE

摘要

Some embodiments of the invention include a rotor assembly for an electric machine, including a rotor hub module. In some embodiments, the rotor hub module can include a body comprising a first and second group of apertures, an output shaft through a generally radially central portion of the body, and a support region along a generally radially outward portion of the body. In some embodiments a plurality of ribs can radially extend from a region of the body adjacent to the output shaft aperture to a region of the body adjacent to the support region. In some embodiments a plurality of rotor laminations can be operatively coupled to a portion of an outer diameter of the support region.
