Abstract: A rotating electrical machine includes a rotor and a stator. A permanent magnet is attached to the rotor. The stator opposes the rotor with a gap provided therebetween, and has an open slot that opens toward the rotor and in which a high-voltage wire is installed. The gap has a gap length at which the sum of losses including a surface loss that occur when the high-voltage wire is excited and the rotor is rotated at a high rotation speed is less than or equal to a threshold that corresponds to a target loss.

Abstract: A rotor core according to an embodiment includes a pair of magnet openings disposed such that a space therebetween widens toward an outer peripheral side and in which a pair of permanent magnets having a magnetic pole direction relative to a radial direction identical to each other are inserted. The magnet openings each have a shape that connects together a first opening portion formed along the profile of the corresponding permanent magnet and a second opening portion that, when the permanent magnet is inserted in the first opening portion, covers, out of corner portions of the permanent magnet, a corner portion closest to the other permanent magnet with an air gap defined therebetween. The second opening portion forms a bridge portion between the second opening portion and the second opening portion of the other magnet opening.

Abstract: A rotor core according to an embodiment has a plurality of magnet openings and cavity portions. The magnet openings are in juxtaposition with each other in a circumferential direction. Permanent magnets are inserted in the magnet openings. The cavity portions are each formed relative to an area sandwiched between two magnet openings, out of the magnet openings, in which the permanent magnets that are mutually adjacent and that have magnetic pole directions relative to a radial direction opposite to each other are inserted.
