Abstract
A fluid-cooled switched reluctance motor, comprised of a stator having a plurality of evenly spaced, radially oriented, like stator poles that define a gap between adjacent stator poles. The stator poles have side walls that are dimensioned wherein adjacent side walls on adjacent stator poles are parallel. Windings are wound about the stator poles, adjacent windings forming a slot of uniform cross-section therebetween. A rotor element is mounted for rotation relative to the stator. The rotor has a plurality of equally spaced, radially oriented like rotor poles. An elongated cooling tube is disposed within each of the slots defined between the windings. The cooling tube has a first end and a second end, and is dimensioned to essentially fill the slot between adjacent windings. A first coolant chamber is disposed at a first end of the stator, and a second coolant chamber is disposed at a second end of the stator.
