Abstract: A rotor includes: a rotor core having a rotor shaft hole into which a rotor shaft is tightened and a plurality of magnet insertion holes provided along a circumferential direction; and a plurality of magnetic pole portions constituted by magnets inserted into the magnet insertion holes. The rotor core includes a cooling portion having a plurality of refrigerant flow passage holes provided radially inward of the plurality of magnetic pole portions and arranged along a circumferential direction, the plurality of refrigerant flow passage holes are arranged on both circumferential end portion sides of each magnetic pole portion, the refrigerant flow passage hole includes an inner radial side apex portion protruding radially inward, and an outer peripheral wall of the refrigerant flow passage hole includes an outer radial side apex portion protruding radially outward.

Abstract: A rotating electric machine unit includes a first rotating electric machine, a second rotating electric machine, and a case having a case main body and a case cover. The first rotating electric machine and the second rotating electric machine each includes a stator core, a multi-phase coil attached to the stator core, and a power distribution member connecting the multi-phase coil. The case cover includes a first bulging portion facing the coil end of the first rotating electric machine, and a third bulging portion facing the coil end of the second rotating electric machine. The third bulging portion is positioned closer to a case main body side than the first bulging portion, and at least a part of a wiring connected to the first rotating electric machine is arranged along a surface of the third bulging portion.

Abstract: A core product includes a first core block and a second core block. The first core block includes: a first block body including a first end surface and a second end surface, and a first resin injection portion; a first solidified resin provided in the first resin injection portion; and a first gate mark integrated with the first solidified resin and protruding outward more than the first end surface. The second core block includes: a second block body including a third end surface and a fourth end surface, and a second resin injection portion; a second solidified resin provided in the second resin injection portion; and a second gate mark integrated with the second solidified resin and protruding outward more than the fourth end surface. The first core block and the second core block are stacked such that the second end surface and the third end surface face each other.
