A lubricant supply system for an electric vehicle includes a lubricant supported electric motor and a lubricant supply line extending from a high pressure source to the lubricant supported electric motor for supplying lubricant to the lubricant supported electric motor. In one arrangement, at least one powertrain component is disposed in fluid communication with the lubricant supply line and fluidly connected in parallel with the lubricant supported electric motor for supplying lubricant to the powertrain component. In an alternative arrangement, the powertrain component is fluidly connected in series with and downstream from the lubricant supported electric motor for supplying lubricant from the lubricant supported electric motor to the powertrain component. In either arrangement, the lubricant supported electric motor is incorporated into an existing lubricant supply system of the vehicle to reduce cost and complexity relative to prior designs which required a dedicated lubricant supply for the lubricant supported electric motor.
