Embodiments of the invention provide an electric machine module including an electric machine. The electric machine includes a rotor assembly. The machine includes an output shaft having a longitudinal axis that is circumscribed by a portion of the rotor assembly. The output shaft comprises an output shaft channel and is coupled to the rotor assembly. A coolant passage system is positioned within the rotor assembly and includes an inlet channel in fluid communication with the output shaft channel and at least one recess. The recess is in fluid communication with the inlet channel. The coolant system can include an outlet channel in fluid communication with the recess. The outlet channel can include at least one coolant outlet so that the coolant outlet is a greater radial distance form the longitudinal axis than is the output shaft channel.
