Rotary electric machine

A rotary electric machine comprising:

• a stator having an annular shape;
• and
• a rotor that is disposed in the stator,
• wherein
• the rotor includes:
• a rotor core;
• and
• a plurality of sets of permanent magnets embedded in the rotor core, each set of the permanent magnets constituting one magnetic pole, the plurality of sets of the permanent magnets disposed in the rotor core in a circumferential direction of the rotor core,
• the rotor core includes:
• a first flux barrier provided on both sides in a rotation direction of the rotor with respect to each set of the permanent magnets;
• and
• a first bridge provided outside the rotor core in a radial direction with respect to the first flux barrier, and
• the first bridge includes:
• a front bridge provided at a front in the rotation direction of the rotor;
• and
• a rear bridge provided at a rear in the rotation direction of the rotor, and
• wherein when a front reference location that is a reference location of the front bridge is an intersection point of a front imaginary line passing through a center axis of the rotor core and a front end of each set of the permanent magnets and an outer circumferential surface of the rotor core in a plane view in which the rotor is viewed from an axial direction, and a rear reference location that is a reference location of the rear bridge is an intersection point of a rear imaginary line passing through the center axis of the rotor core and a rear end of each set of the permanent magnets and the outer circumferential surface of the rotor core in the plane view,
• in at least one set of the permanent magnets among the plurality of sets of the permanent magnets,
• a rear end of the front bridge is disposed at a position away from the front reference location to the rear by θa/24 (radian) or more and θa/8 (radian) or less at a central angle about the center axis, and
• a front end of the rear bridge is disposed at a position away from the rear reference location to the front by 0 (radian) or more and θa/12 (radian) or less at the central angle about the center axis,
• where, θa satisfies Formula (1) described below,
• θa=2π/(Nslot) (1)
• where Nslot in Formula (1) described above means a number of slots of the stator.
