Abstract:
A hybrid cascading lubrication and cooling system (200, 400) for an electrical machine (102) with nested stages is provided. The electrical machine (102) includes an inner nested stage (444) nested with respect to an outer nested stage (446). An oil pump (222) is coupled to an oil pump inlet tube (226) to draw oil from an oil sump (224), and a cooling core (230) to distribute pumped oil within the electrical machine (102). A rotor member (212) is coupled to the inner nested stage (444) and the outer nested stage (446). The rotor member (212) centrifugally pumps oil from the cooling core (230) through inner radial holes (424) and outer radial holes (436) in the rotor member (212) upon rotation about a central axis (216) of the electrical machine (102).
