1. A switched reluctance electric machine, comprising:
- a shaft;
a rotor connected to the shaft;
a stator axially aligned with the rotor and disposed radially outward from the rotor, the stator having;
a plurality of teeth having a rectangular portion;
a winding of wire disposed around each of the rectangular portions of the plurality of teeth to form a plurality of poles and a plurality of triangular voids, the voids being formed between adjacent windings about a radially outer portion of the stator; and
at least one tube disposed within the triangular voids between the windings of wire associated with adjacent poles of the plurality of poles and configured to hold a heat-transferring medium; and
a housing enclosing the shaft, rotor, and stator.

Abstract
A switched reluctance electric machine has a shaft and a rotor connected to the shaft. The electric machine also has a stator axially aligned with the rotor and disposed radially outward from the rotor. The stator has a plurality of teeth, a winding of wire disposed around each of the plurality of teeth to form a plurality of poles, and at least one tube. The at least one tube is disposed between the windings of wire associated with adjacent poles of the plurality of poles and is configured to hold a heat-transferring medium. The switched reluctance electric machine further has a housing enclosing the shaft, rotor, and stator.
