PROBLEM TO BE SOLVED: To provide a technology for improving the efficiency of a rotary machine that comprises a stator configured by assembling a first member with a yoke part and a second member with a tooth part.SOLUTION: A stator 110 is configured by assembling a first member 120 and a second member 130. The first member has a yoke part 121 extending in a circumferential direction. The second member has: a tooth part 140 formed by a tooth base 150 extending in a radial direction and a tooth front end part 160 extending in the circumferential direction; and a coupling part 170 for coupling adjacent tooth front end parts 160 with each other. The tooth front end part has first and second outer peripheral walls 161 and 162 and an inner peripheral wall 163. An angle θ made by a center line T of the tooth part and the first outer peripheral wall (the second outer peripheral wall) is set within a range of 50°≤θ≤60° in a case where six tooth parts 140 are provided.SELECTED DRAWING: Figure 3 |
