PROBLEM TO BE SOLVED: To provide a stator which can prevent motor efficiency from decreasing, ensure rigidity of a stator structure, improve the occupying rate of a conductor and prevent it from decreasing. SOLUTION: A stator iron core 1 involves a plurality of extreme teeth parts 2 whose outside diameters are connected in a ring shape and which protrude in an internal diameter direction is laminated, forms a slot 3 between the extreme teeth parts 2 adjacent to each other. A slot opening part for making a winding machine nozzle 5 pass therethrough which winds a winding 4a directly is fitted on the inner diameter side of the stator iron core 1. The extreme teeth parts 2 are so taper-shaped that they become about twice as thin as the diameter of the winding 4a, being directed from the internal diameter side part 2a to the external diameter side part 2b. The winding part 4 is made roughly orthogonal through an insulator 6 which has even thickness at the same surface of the extreme teeth parts 2 as brushless motor stator. |
