A traction drive system for a vehicle includes a housing, a high-speed motor, a motor controller, a transmission, a cooling system, and a lubricating oil system. The housing defines a motor cavity, an electronics cavity, an oil cavity, and a cooling fluid cavity. The cooling fluid cavity is thermally coupled to each of the motor, electronics, and oil cavities. The high-speed motor is substantially within the motor cavity and coupled to a lubricating oil system fluidically coupled to the oil cavity. The motor controller includes electronics within the electronics cavity. The transmission is mechanically coupled to the high-speed motor and coupled to the lubricating oil system fluidically coupled to the oil cavity. The cooling system is fluidically coupled to the cooling fluid cavity and configured to cool the high-speed motor, the motor controller, and the lubricating oil system. 1. A traction drive system for a vehicle comprising:a housing that defines a motor cavity, an electronics cavity, an oil cavity, a transmission cavity, and a cooling fluid cavity, wherein the cooling fluid cavity is thermally coupled to each of the motor cavity, electronics cavity, and oil cavity;a high-speed motor that is substantially within the motor cavity;a motor controller comprising electronics within the electronics cavity and configured to control a speed of the motor; anda transmission that is substantially within the transmission cavity and mechanically coupled to the high-speed motor,wherein the oil cavity is configured to fluidically couple to a lubricating oil system configured to supply lubricating oil to the motor and the transmission, andwherein the cooling fluid cavity is configured to fluidically couple to a cooling system configured to cool the high-speed motor, the motor controller, and the lubricating oil system.2. The traction drive system of claim 1 , further comprising the lubricating oil system.3. The traction drive system of claim 1 , further comprising the cooling ...
