Rotating electrical machine

A rotating electrical machine comprising:

• a rotor having a rotor core provided with a plurality of magnet holes in a circumferential direction, and permanent magnets embedded in the magnet holes and forming magnetic poles;
• and
• a stator having a plurality of tooth portions which are disposed in the circumferential direction and on which coils are wound, wherein
• the rotor is disposed on an inner circumferential side of the stator with a magnetic gap therebetween,
• an outer circumferential portion of the rotor core has petal portions disposed so as to correspond to the respective magnetic poles and each having an arc shape with a diameter smaller than a rotor diameter, and interpole bridges each located at a non-magnetic portion between the adjacent magnetic poles and disposed on an outer circumferential side with respect to the permanent magnets,
• the interpole bridges each have an outer circumferential surface facing the magnetic gap and formed by two flat surfaces, and
• the two flat surfaces are arranged at an angle to each other such that a connection portion between the two flat surfaces is recessed with respect to the magnetic gap.
