INSULATOR, AND STATOR AND MOTOR COMPRISING SAME

An insulator 5 includes a part 50 to be wound with a coil 7 of a wiring wire with a circular cross section; a first flange 51; and a second flange 52. The first flange 51 is formed at the side of the part 50 closer to a core segment 41. The second flange 52 is formed at the side closer to a distal e...

Summary:An insulator 5 includes a part 50 to be wound with a coil 7 of a wiring wire with a circular cross section; a first flange 51; and a second flange 52. The first flange 51 is formed at the side of the part 50 closer to a core segment 41. The second flange 52 is formed at the side closer to a distal end of a tooth 42. The part 50 to be wound with the coil has a slope 50a continuous with the first flange 51 and inclined so that a height from an upper surface 42a of the tooth 42 increases from the first flange 51 toward the second flange 52. Expression 0 < (-6.8 D + b) ≤ α <30 is satisfied, where b is a constant and 8.3 ≤ b ≤ 11.6 is satisfied, D (mm) is a diameter of the coil, and α (°) is an angle of the slope inclined from the upper surface 42a of the tooth 42 as a reference surface.
