Title:
ROTOR OF DYNAMO-ELECTRIC MACHINE AND DYNAMO-ELECTRIC MACHINE USING THE SAME
Document Type and Number:
Japanese Patent JP2018064374
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide the rotor of dynamo-electric machine capable of improving the characteristics of dynamo-electric machine, by suppressing magnetic flux leakage into a rotor core, thereby efficiently using the magnetic flux of permanent magnets, and to provide a dynamo-electric machine using the same.SOLUTION: In a rotor including multiple permanent magnets 12 arranged in a V-shape opening in an external-diameter direction and forming a magnetic pole in pair, and a rotor core 11 constituted by laminating core sheets 11A having a V-shape opening 11b housing the multiple permanent magnets 12, in the direction of the rotation axis. The core sheet 11A has an inner diameter side cavity 11d1 and an outer diameter side cavity 11d2 formed, respectively, at an inner diameter side end and an outer diameter side end of the V-shape opening 11b, and has a positioning protrusion 11e protruding into the outer diameter side cavity 11d2 and abutting on the permanent magnet 12 and a circumferential end face 11eb and an external-diameter side end face 11ec facing the outer diameter side cavity 11d2.SELECTED DRAWING: Figure 4
