Rotor of rotary electric machine

A rotor of a rotary electric machine, the rotor comprising:

• a rotor core including a plurality of magnetic poles arranged in a circumferential direction around a central axis, each of the magnetic poles including at least two magnet holding slots opposed to each other at intervals in the circumferential direction, a first core portion located between the two magnet holding slots in the circumferential direction, a second core portion located between the two magnet holding slots and the central axis, and a bridge connecting the first core portion and the second core portion;
• and
• a plurality of permanent magnets each arranged in the magnet holding slot, wherein
• when an axis passing through a center in the circumferential direction of the magnetic pole and the central axis is defined as a d-axis and an axis passing through the central axis and a boundary between magnetic poles adjacent in the circumferential direction and extending in a radial direction is defined as a q-axis, in a cross section of the rotor core orthogonal to the central axis,
• the magnetic poles includes two of the magnet holding slots provided on both sides in the circumferential direction of the d-axis, and a core portion located on the q-axis and forming a magnetic path that passes magnetic flux,
• the bridge includes a plurality of first center bridges located between the d-axis and the two magnet holding slots and separated from each other in the circumferential direction, and a coupling element that connects the plurality of first center bridges to each other.
