Abstract
An electrically assisted turbocharger () includes an air cooling system for cooling an electric motor () housed within a motor chamber () in a bearing housing (). An inlet volute () is formed in the bearing housing () on a first side of the electric motor () and an outlet volute () is formed in the bearing housing () on a second side of the electric motor () opposite from the inlet volute (). The inlet volute () accelerates cooling air that is fed into the inlet volute () and directs the cooling air into the motor chamber (). The cooling air travels in an axial direction through the motor chamber () from the inlet volute () to the outlet volute (), thereby cooling the electric motor (). The outlet volute () decelerates the cooling air and directs the cooling air out of the motor chamber ().
