Abstract
Official abstract text for this publication.
A rotating electric machine includes a non-rotating member, a stator fixed to the non-rotating member, a field coil fixed to the non-rotating member, disposed on an inner diameter side of the stator, and having an iron core and a winding wound around the iron core, and a rotor rotatably disposed between the stator and the field coil. The rotor has, at a portion facing the stator, different radial dimensions with respect to a rotary shaft of the rotor between a one end of the rotor in an extending direction of the rotary shaft and a portion different from the one end in the extending direction.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rotating electric machine, comprising: a non-rotating member; a stator fixed to the non-rotating member; a field coil fixed to the non-rotating member, disposed on an inner diameter side of the stator, and having an iron core and a winding wound around the iron core; and a rotor rotatably disposed between the stator and the field coil, wherein the rotor has, at a portion facing the stator, different radial dimensions with respect to a rotary shaft of the rotor between a one end of the rotor in an extending direction of the rotary shaft and a portion different from the one end in the extending direction. 2. The rotating electric machine according to claim 1 , wherein the rotor has, at the portion, a groove portion provided at the one end in the extending direction and on a surface facing the stator, and due to the groove portion, the radial dimension of the portion at the one end in the extending direction and the radial dimension of the portion at a portion different from the one end in the extending direction are different. 3. The rotating electric machine according to claim 1 , wherein the rotor has, at the portion, an inclined surface facing the iron core, and inclined so as to separate from the iron core as going toward a center in the extending direction from the one end in the extending direction, and due to the inclined surface, the radial dimension of the portion at the one end in the extending direction and the radial dimension of the portion at a portion different from the one end in the extending direction are different. 4. The rotating electric machine according to claim 3 , wherein the field coil has an outer edge in the radial direction extending along the inclined surface of the rotor.
