WIPO Patent Application WO/2015/029256
Kind Code:
A1
Abstract:
A synchronous electric motor is equipped with a stator having nine teeth which are divided into three phases each having adjacent three teeth and around which coils (2) are concentrically wound. Among the three teeth constituting each phase, the circumferential direction width (w1) of the end (30b) of a central tooth (30) is formed narrower than the circumferential direction widths (w2, w3) of the ends (31b, 32b) of the teeth (31, 32) on both sides of the central tooth (30), and the tooth thickness (t1) of the end (30b) of the central tooth (30) is formed thinner than the tooth thicknesses (t2, t3) of the ends (31b, 32b) of the teeth (31, 32) on both sides.
