Abstract
Official abstract text for this publication.
A multi-phase iron-core reactor has an iron core and windings. The iron core includes an outer iron core and an inner iron core. The outer iron core has teeth on which the N-phase windings are wound. The inner iron core faces the teeth through gaps, and has a shape so as to be able to provide at least two gap sizes in a selective manner.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-phase iron-core reactor comprising an iron core and windings, wherein the iron core includes an outer iron core and an inner iron core; the outer iron core has three teeth on which the three-phase windings are wound, each of the three teeth extends toward a central axis of the outer iron core, the three teeth are arranged 120° out of phase with each other with respect to a center which is the central axis of the outer iron core; the inner iron core has a first portion, which faces each of the three teeth in first phase and outwardly curves in the radial direction, and a second portion, which faces each of the three teeth in second phase, which is 60° out of phase with respect to the center which is the central axis of the outer iron core, from the first phase and outwardly curves in the radial direction so as to be different from the first portion; the inner iron core is arranged so as to form a first gap when the first portion is opposed to each of the three teeth in the position of the first phase, and is arranged so as to form a second gap, the size of which is different from that of the first gap, when the second portion is opposed to each of the three teeth in the position of the second phase. 2. The multi-phase iron-core reactor according to claim 1 , wherein the outer iron core is constituted of a lamination of outer cores made of polygonal electrical steel sheets. 3. The multi-phase iron-core reactor according to claim 1 , wherein the inner iron core is constituted of a lamination of inner cores made of electrical steel sheets. 4. The multi-phase iron-core reactor according to claim 1 , wherein the inner iron core is 120° symmetrical in shape with respect to the center which is the central axis of the outer iron core. 5. The multi-phase iron-core reactor according to claim 1 , wherein the inner iron core is rotatable about a central axis. 6. The multi-phase iron-core reactor according to claim 1 , wherein the teeth and the coil for each phase are equally divided by M, which is a whole number.
