<P>PROBLEM TO BE SOLVED: To provide a salient pole concentrated winding stator for a motor which prevents looseness of winding at a winding end part of the winding, thereby stably holding connection at a winding connection part configured to connect the winding end part thereto. <P>SOLUTION: An insulator 12 has a coil looseness prevention mechanism 60 on the outside in a radial direction of a trunk 24 configured to wind an unfastened winding 14 therearound. The coil looseness prevention mechanism 60 prevents looseness of the winding 14 between a first winding end 41 and a winding connection part 14a of the winding 14 of a coil 13. The winding looseness prevention mechanism 60 includes: a first guide part 30 having a guide surface 30a to guide the winding 14 between the first winding end 41 and the winding connection part 14a of the winding 14 of the coil 13; a roller 61 to hold the winding 14 between the roller 61 and the first guide part 30; and a second guide part 31 having a contact surface 31b configured to be contacted with the roller 61. The guide surface 30a of the first guide part 30 and the contact surface 31b of the second guide part 31 are formed to gradually decrease their mutual distance toward the first winding end 41 of the winding 14. <P>COPYRIGHT: (C)2013,JPO&INPIT |
