Abstract
A power generator that operates at a reduced temperature level includes a flux shunt that reduces the amount of fringing magnetic flux axially impinging upon a stator, flange, and multiple keybars during operation of the generator. By reducing the amount of axially impinging flux, the flux shunt reduces an operating temperature of the stator and flange and reduces a voltage differential between keybar voltages induced by the flux in the multiple keybars.
Claims22
A power generator comprising:
- a rotor having a radial outer surface;
- a stator assembly comprising:
- an approximately cylindrically-shaped stator core comprising an outer surface, a radial inner surface, and two ends;
- and
- a flux shunt circumferentially disposed adjacent to the inner surface of the stator core at approximately an end of the two ends of the stator core, the flux shunt having a convex outer surface disposed adjacent to the radial inner surface of the stator core and a concave inner surface disposed adjacent to the radial outer surface of the rotor;
- and
- a plurality of axially oriented keybars circumferentially disposed adjacent to the outer surface of the stator core;
- wherein the rotor is rotatably disposed inside of the stator.

A power generator comprising:
- a stator having a radial inner surface;
- and
- a flux shunt disposed adjacent to the inner surface of the stator, the flux shunt having a convex outer surface disposed adjacent to the radial inner surface of the stator.
A power generator comprising:
- a stator;
- a rotor rotatably disposed within the stator, the rotor having a radial outer surface;
- a flux shunt disposed adjacent to the inner surface of the stator, the flux shunt having a concave inner surface disposed adjacent to the radial outer surface of the rotor.
A power generator comprising:
- an approximately cylindrically-shaped stator comprising a stator core, an inner surface, and two ends;
- a flux shunt circumferentially disposed adjacent to the inner surface of the stator at approximately an end of the two ends of the stator;
- a rotor rotatably disposed inside of the stator;
- and
- wherein a rotation of the rotor produces a fringing magnetic flux that axially impinges upon the end of the stator, and wherein the flux shunt causes the magnetic flux axially impinging upon the end of the stator to be less than a magnetic flux that would axially impinge upon the end of the stator in the absence of the flux shunt.
