Rotor core

A rotor core, comprising:

• an annular laminated core formed by stacking a plurality of electrical steel sheets;
• and
• a plurality of permanent magnets forming a plurality of magnetic poles arranged circumferentially, wherein
• the laminated core includes, in each of the plurality of magnetic poles, a one side magnet hole that is provided on one side in a circumferential direction with respect to a d-axis and into which the permanent magnet is inserted, an other side magnet hole that is provided on the other side in the circumferential direction with respect to the d-axis and into which the permanent magnet is inserted, an intermediate magnet hole that is provided between the one side magnet hole and the other side magnet hole and into which a plurality of the permanent magnets is inserted so as to be arranged in a convex shape pointing radially outward, a first outer bridge portion provided between a radially outer end of the one side magnet hole and an outer edge of the laminated core, a second outer bridge portion provided between a radially outer end of the other side magnet hole and the outer edge, a first inner bridge portion provided between the one side magnet hole and the intermediate magnet hole and connecting a radially inner portion of the laminated core and a radially outer portion of the laminated core, and a second inner bridge portion provided between the other side magnet hole and the intermediate magnet hole and connecting the radially inner portion and the radially outer portion.
