Abstract: A rotor is provided for an electric motor. The rotor shaft is located within a central opening of the rotor core. The central opening is sized larger than the rotor shaft such that a circumferential gap exists between the rotor core and the rotor shaft while the shaft is located by protrusions in the central opening of the rotor core. The circumferential gap is filled with a resin.

Abstract: An electrical machine includes a stator including a plurality of stator windings; and a rotor in magnetic cooperation with the stator. The rotor includes a plurality of cooling passages extending therethrough, each cooling passage including an inlet for receiving oil and an outlet for discharging the oil. The electrical machine includes a rotating oil distribution member coupled to the rotor, the oil distribution member including a radially inward portion and a radially outward portion, the radially outward portion being disposed adjacent to the inlets of the plurality of cooling passages. A stationary oil delivery nozzle is constructed to discharge oil toward the radially inward portion of the oil distribution member. The oil distribution member is constructed to receive the oil discharged by the oil delivery nozzle, and to direct the oil to the inlets of the cooling passages to cool the rotor.
