A motor driven assembly includes a motor having a motor inlet and a motor outlet, a shaft, and a rotor spaced radially outwards from the shaft. A cooling flow passage is located between the shaft and the rotor. The cooling flow passage fluidly connects the motor inlet and the motor outlet. A compressor is in fluid communication with the motor outlet. The compressor includes a compressor outlet that is in fluid communication with the motor inlet.

1. A motor driven assembly comprising: a motor having a motor inlet, a motor outlet, a shaft, and a rotor spaced radially outwards from said shaft;a cooling flow passage located radially outward from said shaft and radially inward from an inner surface of said rotor that fluidly connects said motor
1. A motor driven assembly comprising: a motor having a motor inlet, a motor outlet, a shaft, and a rotor spaced radially outwards from said shaft;a cooling flow passage located radially outward from said shaft and radially inward from an inner surface of said rotor that fluidly connects said motor inlet and said motor outlet, wherein said cooling flow passage includes a cooling flow passage inlet located at a first end of said rotor and a cooling flow passage outlet located at a second end of said rotor; anda compressor in direct fluid communication with said motor outlet, said compressor having a compressor outlet in fluid communication with said motor inlet; anda heat exchanger outside of said motor and in fluid receiving communication with said compressor outlet. 2. The assembly as recited in claim 1, wherein said motor includes a second motor inlet and a second cooling flow passage that fluidly connects the second motor inlet and the motor outlet. 3. The assembly as recited in claim 2, wherein said motor includes a motor housing, said rotor that is rotatable about an axis, and a stator located radially outward from said rotor, and said second cooling flow passage includes a stator passage between said stator and said motor housing. 4. The assembly as recited in claim 2, wherein said second cooling flow passage further includes a stator-rotor passage between said stator and said rotor. 5. The assembly as recited in claim 2, wherein said motor includes a motor housing and a stator located radially outward from said rotor, said second cooling flow passage being between said stator and said rotor. 6. The assembly as recited in claim 3, further comprising a valve near said motor outlet for selectively directing air to said compressor. 7. The assembly as recited in claim 1, wherein said cooling flow passage is configured to accept cooling air. 8. The assembly as recited in claim 1, wherein said cooling flow passage is located radially outward from an outer surface of said shaft and radially inward from said inner surface of said rotor. 9. The assembly as recited in claim 1, wherein said cooling flow passage extends from a first end of said rotor to a second end of said rotor. 10. The assembly as recited in claim 1, wherein said cooling flow passage is configured to allow a cooling fluid to flow from a first end of said rotor to a second end of said rotor. 11. A motor driven assembly comprising: a motor having a motor inlet, a motor outlet, a shaft, and a rotor spaced radially outwards from said shaft;a cooling flow passage between said shaft and said rotor that fluidly connects said motor inlet and said motor outlet for accepting cooling air;a compressor in direct fluid communication with said motor outlet, said compressor having a compressor outlet in fluid communication with said motor inlet; anda heat exchanger outside of said motor and in fluid receiving communication with said compressor outlet. 12. The assembly as recited in claim 11, wherein said motor includes a second motor inlet and a second cooling flow passage that fluidly connects the second motor inlet and the motor outlet. 13. The assembly as recited in claim 12, wherein said motor includes a motor housing, said rotor that is rotatable about an axis, and a stator located radially outward from said rotor, and said second cooling flow passage includes a stator passage between said stator and said motor housing. 14. The assembly as recited in claim 12, wherein said second cooling flow passage further includes a stator-rotor passage between said stator and said rotor. 15. The assembly as recited in claim 12, wherein said motor includes a motor housing and a stator located radially outward from said rotor, said second cooling flow passage being between said stator and said rotor. 16. The assembly as recited in claim 11, wherein said cooling flow passage extends from a first end of said rotor to a second end of said rotor. 17. The assembly as recited in claim 11, wherein said cooling flow passage is configured to accept cooling air. 18. The assembly as recited in claim 11, wherein said compressor is configured to accept a cooling fluid from said motor outlet prior to said cooling fluid entering a heat exchanger.
