形する。 The thin steel plate 13 constituting the iron core 12 of the rotor 11 has a slot portion 14 and a ventilation path portion 15 formed by integral punching, and as shown in FIG. A shape is formed as if a circular arc portion 13c is formed at each end thereof, and during the punching process, a rotor shaft hole 16, a coil receiving insertion hole 17, etc. are punched at the connecting portion between the arm 13b and the circular arc portion 13c. Shape. Further, a coil receiving and locking groove 18 is formed by punching at the boundary between the slot portion 14 and the ventilation passage portion 15 on the edge of the arm 13b.

２４が収納されている。 Further, a coil receiver 21 is installed in the small groove 18 formed in the direction of the rotor shaft 19. This coil receiver 21
has a square-shaped cross section, and its both edges are fitted into the small grooves 18 to form a ventilation passage 22 at the base of the arm 13b of the central part 13c, and both ends of the coil receiver 21 are connected to the sides of the iron core 12. Make the coil receiver 2 stick out.
Another coil receiver 21 is provided at an inner circumferential position than 0. Further, a slot 23 is provided at a position corresponding to the slot portion 14 on the outside of the coil receiver 21, and a coil 24 is housed in the slot 23.
