Abstract:
A fluid-cooled switched reluctance motor, comprising:a stator having a plurality of evenly spaced, radially oriented, like stator poles that define a gap between adjacent stator poles, said stator poles having side walls dimensioned wherein adjacent side walls on adjacent stator poles are parallel;windings wound about said stator poles, adjacent windings forming a slot of uniform cross-section therebetween;a rotor element mounted for rotation relative to said stator, said rotor having a plurality of equally spaced, radially oriented like rotor poles;an elongated cooling tube disposed within each of said slots between said windings, said cooling tube having a first end and a second end, and being dimensioned to essentially fill said slot between adjacent windings; anda first coolant chamber disposed at a first end of said stator, and a second coolant chamber disposed at a second end of said stator, said first coolant chamber connected to said first end of each of said cooling tubes, and said second coolant chamber connected to said second end of each of said cooling tubes, wherein each of said cooling tubes connects said first coolant chamber to said second coolant chamber.
