Title: ROTOR FOR ROTATING ELECTRICAL MACHINE AND ROTATING ELECTRICAL MACHINE
Abstract:
This rotor is provided with a rotor core (31), a plurality of first conductors (331), a second conductor provided on one end side in the axial direction of the rotor core (31), and a third conductor provided on the other end side in the axial direction of the rotor core (31). When n is the harmonic order and p is the number of electrode pairs, the second conductor connects, to each other, one ends of the first conductors (331) inserted into two slots (31a) which are positioned at a mechanical angle of 360/n/p, and the third conductor connects, to each other, the other ends of the first conductors (331) inserted into the two slots (31a). The cross-sectional areas of the second conductor and the third conductor are no less than the cross-sectional area of the first conductors (331).
