Self cooling motor system

An internally cooled motor assembly comprising:

• a frame,
• a shaft assembly comprising a shaft having an open end and a sealed end, wherein said open end comprises an inlet and an outlet interconnected in a fluid communicating relation by a channel extending therebetween,
• said frame comprising bearings disposed at opposite ends, said shaft supported in said frame in a rotational configuration via said bearings,
• an armature assembly mounted to said shaft and structured to rotate therewith, said armature assembly comprising a plurality of poles extending outwardly and substantially perpendicular to said shaft,
• each of said plurality of poles having a proximal end disposed adjacent said shaft and a distal end disposed outwardly from said shaft,
• a winding assembly comprising a plurality of windings affixed to said armature assembly, wherein at least one of said plurality of windings is disposed in an overlying relation to a corresponding one of each of said plurality of poles,
• each of said windings comprising an inlet aperture and an outlet aperture,
• each of said windings further comprising a fluid passage extending lengthwise therethrough between said inlet aperture and said outlet aperture to facilitate passage of a fluid heat transfer media therethrough,
• an inlet fluid transfer slip ring assembly interconnected to said open end of said shaft and disposed in a fluid transferring configuration with said inlet of said shaft,
• said outlet of said shaft interconnected to said inlet aperture of each of said windings and disposed in a fluid transferring relation therewith,
• an outlet fluid transfer slip ring assembly interconnected to said outlet aperture of each of said windings and disposed in a fluid transferring orientation therewith, wherein said outlet aperture of each of said windings is disposed proximate said distal end of said at least one pole extending outwardly from said shaft,
• each of said windings comprising a helix configuration between said inlet aperture and said outlet aperture,
• said helix configuration structured such that rotation of said shaft at a predetermined speed creates a centrifugal force sufficient to maintain a predetermined flowrate of said fluid heat transfer media through said fluid passage of each of said windings, wherein a flow of said fluid heat transfer media through each of said windings is in a direction from said inlet aperture to said outlet aperture of each said windings along a radial flow path, and
• wherein said predetermined flowrate of said fluid heat transfer media through said fluid passage of each of said windings results in a transfer of a predetermined amount of heat from each of said windings to said fluid heat transfer media, thereby maintaining an operating temperature of said internally cooled motor assembly within a predetermined operating range.

A self cooling motor system comprising:

• an internally cooled direct current motor assembly, wherein said motor assembly comprises:
• a frame comprising bearings disposed at opposite ends, said bearing supporting a shaft in a rotational configuration relative to said frame,
• an armature assembly mounted to said shaft and structured to rotate therewith,
• a winding assembly affixed to at least a portion of said armature assembly in an overlying relation,
• said winding assembly comprising at least one winding having an inlet aperture and an outlet aperture and a fluid passage extending lengthwise therebetween to permit a flow of a fluid heat transfer media therethrough,
• a fluid inlet conduit disposed and interconnected in a fluid communicating relation with said shaft,
• said shaft being further interconnected to said inlet aperture of said winding, said shaft structured to permit said flow of said fluid heat transfer media from said fluid inlet conduit to said inlet aperture of said winding,
• a fluid outlet manifold interconnected in a fluid communicating relation with said outlet aperture of said winding,
• said winding comprising a helix configuration between said inlet aperture and said outlet aperture, wherein said outlet aperture is disposed in an outwardly extending orientation relative to said inlet aperture and said shaft,
• said helix configuration structured such that rotation of said shaft within a predetermined operating speed range generates a centrifugal force sufficient to maintain a predetermined flowrate of said fluid heat transfer media through said winding from said inlet aperture to said outlet aperture, and
• wherein said predetermined flowrate of said fluid heat transfer media through said winding results in a transfer of a predetermined amount of heat from said winding to said fluid heat transfer media, thereby maintaining an operating temperature of said internally cooled motor assembly within a predetermined operating temperature range, and
• a heat transfer assembly disposed in a fluid communicating relation between said fluid outlet manifold and said fluid inlet conduit of said internally cooled direct current motor assembly.
