In direction outside outer rotor die sudden polar

摘要

PROBLEM TO BE SOLVED: To provide an outer rotor type salient pole concentrated winding motor capable of preventing an insulator from escaping from teeth of a stator and capable of surely preventing the insulator from contacting a rotor.;SOLUTION: An insulator 13 includes: an outer barrier 33 that extends from one end part in the axial direction of the side collar portion 31 of the circumference to the outer radial direction; an engaging part 33a that is disposed on one end side in the circumferential direction of the outer barrier 33 and is formed in a convex form projected toward the outer circumferential direction; and an engaged part 33b that is disposed on the other end side in the circumferential direction of the outer barrier 33 and is formed in a concave form projected toward the inner circumferential direction. When a plurality of the insulators 13 are respectively inserted into a plurality of teeth 11b, an engaging part 33a and an engaged part 33b of adjoining insulators 13 are fitted into each other.;COPYRIGHT: (C)2012,JPO&INPIT
