Abstract
A three-phase winding is energized so that a phase difference θe1 between each set is 30±60×n [deg] in an electrical angle. A tip portion of the teeth has a skew structure having a plurality of skew forming parts divided in an axial direction so as to be displaced by a predetermined angle θe2 in a circumferential direction in the electrical angle. A relational expression θe1>θe2 is satisfied. When a radial distance between the teeth and a circumscribed circle of a rotor core is set to a, and a radial distance between an outermost part of a permanent magnet located on the outermost side in a radial direction in a permanent magnet and the circumscribed circle is set to b, a relational expression a/b<1 is satisfied.
