Rotary electric machine

A rotary electric machine, comprising:

• a stator including a yoke portion configured in an annular shape, and a plurality of teeth portions configured to protrude from a circumferential edge part of the yoke portion in a radial direction of the yoke portion, and in which an electromagnetic coil is provided in slots formed between adjacent ones of the teeth portions;
• and
• a rotor configured to retain a plurality of permanent magnets facing toward the teeth portions,
• wherein the plurality of permanent magnets are configured to include a same number of a first magnet in which a magnetic field thereof is oriented in a radially outward direction of the yoke portion, a second magnet adjacent to the first magnet and in which a magnetic field thereof is oriented in a clockwise direction of the yoke portion, a third magnet adjacent to the first magnet and in which a magnetic field thereof is oriented in a counterclockwise direction of the yoke portion, and a fourth magnet adjacent to the third magnet and in which a magnetic field thereof is oriented in a radially inward direction of the yoke portion,
• the teeth portions each include a base portion configured to protrude from an inner circumferential edge part of the yoke portion in the radially inward direction of the yoke portion, a flange portion disposed in closer proximity to the rotor than the base portion, and configured to be wider than the base portion, and an expanding portion interposed between the base portion and the flange portion, and configured to become wider in an expanding manner from the base portion toward the flange portion;
• an angle of intersection between the base portion and the expanding portion is 108° to 130°, and
• a distance from an inner circumferential side end part to an outer circumferential side end part of the flange portion is 0.2 mm to 2.0 mm.
