Abstract:
This insulator 5 comprises a coil-winding part 50 on which a coil 7 is to be wound; a first flange part 51 provided on a core segment 41 side of the coil-winding part 50 and having a coil lead-in groove 53 that guides the coil 7 to the coil-winding part 50; and a second flange part 52 provided on the tip side of a tooth 42 of the coil-winding part 50. A projection 54 having a height H from a surface of the coil-winding part 50 is formed in a corner between the surface of the coil-winding part 50 and an inner surface 52a of the second flange part 52. Assuming that the half value of the wire diameter of the coil 7 is taken as r, the height H is within the range of 0.9r (1 + tan30°) < H < 1.1r (1 + tan30°).
