Spray cooled motor system

Abstract

A spray cooled motor system with a motor housing with an interior and an exterior, a stator mounted within the interior of the motor housing, a rotor mounted within the interior of the motor housing, a coil winding mounted within the interior of the motor housing, a plurality of atomizers configured to spray a coolant on at least one of the stator and the rotor, a coolant pump in fluid communication with the plurality of atomizers; and an output shaft extending through an output shaft aperture from the interior to the exterior of the motor housing.

I/We claim:  
     
         1 . A spray cooled motor comprising: 
 a motor housing with an interior and an exterior;    a stator mounted within the interior of the motor housing;    a rotor mounted within the interior of the motor housing;    a coil winding mounted within the interior of the motor housing;    a plurality of atomizers configured to spray a coolant on at least one of the stator and the rotor; and    a coolant pump in fluid communication with the plurality of atomizers.    
     
     
         2 . A spray cooled motor as recited in  claim 1 , and wherein the motor is a variable switched reluctance motor.  
     
     
         3 . A spray cooled motor as recited in  claim 1 , and wherein the output shaft aperture is sealed with the motor housing such that the coolant is contained within the interior of the motor housing.  
     
     
         4 . A spray cooled motor as recited in  claim 3 , and further comprising an output shaft extending through an output shaft aperture from the interior to the exterior of the motor housing, and wherein the output shaft aperture is sealed with the motor housing with a sliding elastomeric seal.  
     
     
         5 . A spray cooled motor as recited in  claim 3 , and further comprising an output shaft extending through an output shaft aperture from the interior to the exterior of the motor housing, and wherein the output shaft aperture is sealed with the motor housing with a ferro-fluidic seal.  
     
     
         6 . A spray cooled motor as recited in  claim 1 , and further comprising: 
 motor controls mounted within the motor housing; and    a plurality of control atomizers configured to spray coolant on the motor controls.    
     
     
         7 . A spray cooled motor as recited in  claim 1 , and wherein the coolant pump is mounted within the motor housing.  
     
     
         8 . A spray cooled motor as recited in  claim 1 , and further comprising heat transfer fins on the exterior of the motor housing.  
     
     
         9 . A spray cooled motor as recited in  claim 1 , and further comprising: 
 heat transfer fins on the exterior of the motor housing; and    a condensation conduit adjacent the motor housing such that vaporized coolant passing through the condensation conduit is condensed.    
     
     
         10 . A spray cooled motor as recited in  claim 1 , and further comprising an output shaft extending through an output shaft aperture from the interior to the exterior of the motor housing.  
     
     
         11 . A spray cooled motor as recited in  claim 1 , and further wherein the motor is electronically coupled to an output on the exterior of the motor housing.  
     
     
         12 . A spray cooled motor as recited in  claim 1 , and further wherein the rotor includes spaced apart poles with a polymer filler inserted between the spaced apart poles, thereby creating a continuous outer surface.  
     
     
         13 . A spray cooled motor as recited in  claim 1 , and further comprising: 
 motor power switching controls mounted within the motor housing; and    a plurality of control atomizers configured to spray coolant on the motor power switching controls.
