<p>A rotor is provided with: a rotor core formed by laminating a plurality of electromagnetic steel sheets; a plurality of slots which are arranged at equiangular intervals in the periphery of the rotor core, and penetrate in the axial direction of the rotor core; and permanent magnets which are mounted to each of the plurality of slots. A plurality of slot-holes which have the same shape and which form the plurality of slots are formed at equiangular intervals in the peripheral section of the plurality of electromagnetic steel sheets, and protrusions are formed in the inner edges of the plurality of slot-holes. The plurality of electromagnetic steel sheets are laminated so that, between electromagnetic sheets which are vertically adjacent, a specified slot-hole having a protrusion is staggered in the circumferential direction by a specified phase-shift amount. Thus, in each slot, a plurality of protrusions are arranged at intervals in the axial direction of the slot. The permanent magnets are fixed in every slot so as to make contact with and deform the protrusions.</p> |
