Thermal management techniques for an electric motor of a vehicle, the electric motor comprising a rotor and a stator include an oil supply system configured to supply oil for cooling the electric motor, end plates defined by the rotor, the end plates defining a first portion of an internal oil channel configured to route oil through the rotor to thereby cool the rotor, and a hollow rotor shaft defined by the rotor, the hollow rotor shaft defining a second portion of the internal oil channel, wherein the end plates are configured to retain the rotor in place and further define external oil channels configured to spray/splash the oil that flowed through the internal oil channel onto windings of the stator to thereby cool the stator.
