<P>PROBLEM TO BE SOLVED: To provide a motor having a coil to form a stator by smoothly allowing stator core pieces to be annular ring shapes after mounting the coil on the stator core pieces. <P>SOLUTION: The motor has a stator 21 including: a stator core 41 with a stator core pieces 45 connected thereto; and a coil 20 to be inserted to be disposed around slot parts. The coil includes: a pair of slot insertion portions 53, 54 having inclination angles being substantially the same as angles along the inclination of tooth parts oriented to an axial center when the stator core pieces are connected to be the annular ring shapes; and a pair of coil transition parts 55, 56 for connecting the edges of the pair of slot insertion portions on the axial end surfaces 41a of the stator core. The coil transition parts are formed by bending outward in a diameter direction so as to meet the axial end surfaces of yokes after the slot insertion portions are projected from the slot parts, and also include slopes 57, 58 whose axial heights are inclined from one edges to the other edges. <P>COPYRIGHT: (C)2012,JPO&INPIT |
