PURPOSE:To simplify a winding work, to improve the insulation and to prevent a coil from deforming or displacing by setting the flatness degree of a magnet wire to a predetermined range, winding it in one row, and so forming a flat surface including a U-shaped portion formed on a coil end as to incline the surface at a predetermined angle. CONSTITUTION:A flat magnet wire 22 used to form a coil 21 is made of a flat enameled wire having 5-20 of flatness degree, the wire 22 is wound in one row to be formed in a hexagonal shape to form a coil 21. A U-shaped portion 24 is formed at the central portion of the end 23 of the coil 21. In this case, the flat surface 25 including the portion 24 is so formed as to incline at an angle theta2 of 15-45 deg. with respect to a flat surface 27 for coupling the center 26 of the portion 24 with the central axis 11 of a stator 8.
