Rotating electric machine with magnet insertion hole arrangement
Abstract:
The rotating electric machine includes: a rotor; and a stator, wherein the rotor includes: a rotor core having a magnet insertion hole group including a plurality of magnet insertion holes; and a permanent magnet group including a plurality of permanent magnets inserted in the plurality of magnet insertion holes of the magnet insertion hole group, respectively, wherein the plurality of magnet insertion holes are arranged side by side in a shape convex toward a center of the rotor from a radially-outer side surface of the rotor core, wherein the permanent magnet group forms one magnetic pole, wherein, in a part of the rotor core between the radially-outer side surface and the magnet insertion hole group, a magnetic slit is formed to extend in a shape convex toward the center of the rotor from the radially-outer side surface, and wherein the magnet insertion hole group includes three magnet insertion holes.
