Abstract

See full text

An electrical machine assembly includes a shaft rotatable about an axis of an electric machine and first and second endcaps mounted to the shaft. The first endcap includes a first endcap coolant channel. The second endcap includes a second endcap coolant channel. A rotor is mounted to the shaft axially between the first and second endcaps. The rotor includes first rotor coolant channels and second rotor coolant channels. The first rotor coolant channels are configured to communicate liquid coolant that is received from the first endcap coolant channel axially through the rotor in a first direction. The second rotor coolant channels are configured to communicate liquid coolant that is received from the second endcap coolant channel axially through the rotor in a second direction that is opposite the first direction.
