PROBLEM TO BE SOLVED : To provide a permanent-magnet motor wherein a rare short circuit can be prevented from occurring in an interphase portion of coils and magnetization can be carried out with stability. SOLUTION : With respect to the permanent-magnet motor, permanent magnets 6 are formed by applying voltage for magnetization to between windings 4b and 4c in two phases electrically connected with each other at a neutral point N and thereby magnetizing unmagnetized magnetic members 16. A plurality of magnetic pole portions V1, V2, V3, V4, W1, W2, W3, and W4, bundled in loops, are formed in the windings 4b and 4c. The windings 4b and 4c are wound on a stator core 3 so that the power line-side magnetic pole portion V1 of either winding 4b does not adjoin to the power line-side magnetic pole portion W1 of the other winding 4c. |
