ROTOR |
| 摘要 |
A rotor core of a rotor includes: a plurality of protrusions formed on at least a step-skew boundary side; and a tubular non-magnetic ring mounted on outer peripheries of a plurality of permanent magnets so as to cover the boundary. The non-magnetic ring includes a plurality of inner diameter bulging portions. Each of the permanent magnets and each of the protrusions are brought into abutment against the corresponding inner diameter bulging portions. |

1. A rotor having a plurality of magnetic poles and a step-skew structure with two or more stages, the rotor comprising a rotor core comprising:
a plurality of protrusions formed on at least a step-skew boundary side; and a tubular non-magnetic ring mounted on outer peripheries of the plurality of magnetic poles so as to cover the step-skew boundary, the non-magnetic ring comprising a plurality of inner diameter bulging portions, each of the plurality of magnetic poles and each of the plurality of protrusions being brought into abutment against the corresponding inner diameter bulging portions. |
