ABSTRACT:
An electrically controlled turbocharger has a motor mounted on a shaft in a motor housing between a turbine and compressor. Oil is sprayed onto the motor stator to cool the stator. An oil gallery is disposed above the stator to receive lubricating oil and contains apertures that perform as jets to allow oil to be sprayed directly on the motor stator. A coolant jacket is formed in the turbocharger housing between the turbine and the motor to allow liquid coolant to circulate therein and dissipate heat from the turbine end prior to reaching the motor components. Other embodiments provide for a stator component to be submerged in flowing cooling oil.
