ROTOR |
| 摘要 |
A rotor includes a rotor iron core in which magnet insertion holes that are arrayed in a radial direction so as to be convex toward an inner peripheral side are provided for each magnetic pole, and in which the magnet insertion holes are arranged in a circumferential direction according to the number of magnetic poles, and flat-shaped permanent magnets that are inserted respectively in the magnet insertion holes, wherein the magnet insertion holes, which are arranged on an innermost peripheral side and adjacent to each other in a circumferential direction are provided in such a manner that the width of the magnet insertion hole gradually becomes larger toward the inner peripheral side such that the width of the iron core between the adjacent magnet insertion holes in a circumferential direction is constant in a radial direction. |

1. A rotor comprising:
a rotor iron core in which a multi-layered magnet insertion holes that are arrayed in a radial direction so as to be convex toward an inner peripheral side are provided for each magnetic pole, and in which the multi-layered magnet insertion holes are arranged in a circumferential direction according to a number of magnetic poles; and flat-shaped permanent magnets, each of which is inserted into the respective magnet insertion holes, wherein the width of the iron core between the adjacent magnet insertion holes, which are arranged on an innermost peripheral side and adjacent to each other in the circumferential direction, is constant, and the width of each of the holes gradually becomes larger toward the inner peripheral side. |
