Abstract
An electric drive unit includes an electric motor having a rotor shaft that defines a hollow that is accessible via an opening defined at an axial end of the rotor shaft. The hollow defines a portion of a fluid flow path. The electric drive unit also includes an output shaft that extends into the hollow through the opening. The electric drive unit further includes a baffle that extends into the hollow through the opening. The baffle is arranged to redirect fluid flowing along the fluid flow path away from a portion of at least one of the rotor shaft and the output shaft.
