塊状回転子、かご形誘導回転電機、およびかご形誘導回転電機の設計方法

Japanese Patent JP7168680

B2

This solid rotor (10) used in a squirrel cage induction rotating electric machine includes: a shaft part which extends in the axial direction and is rotatably supported; a columnar rotor core part (13) which is integrally formed coaxially with the shaft part and has a greater diameter than the shaft part, and in which are formed rotor slots (14) that are disposed with gaps therebetween in the circumferential direction and extend in the axial direction; and a plurality of conductor bars (16) which penetrate through the inside of the rotor slots (14) and are coupled to each other on both outer sides in the axial direction of the rotor core part (13). The two mutually opposing walls of each of the rotor slots (14) incline by at least a predetermined angle in the circumferential direction with respect to a plane that includes the axis of rotation of the shaft part. When viewed outward in the radial direction from the axis of rotation of the shaft part, regions where a portion of a plurality of conductor bars (16) among the plurality of conductor bars (16) are present and regions where the same is not present are alternately disposed in the circumferential direction.
