れている。 In the figure, 2 is a stator core, and a yoke 2 is provided on the outer periphery of the stator core. The outer periphery of this yoke part 1 is formed by a flat part 3, and is located inside the outer periphery of the stator core 2. A slot 4 into which a coil is inserted is formed inside the yoke part 1 of the stator core 2, and an opening for inserting the coil is formed in the yoke part 1 facing approximately at the center of the slot 4. A portion 5 is formed. The side wall of the opening 5 is formed in a semicircular shape so that the entrance of the opening 5 is wide. The toothed portion 6 located between the two slots 4 and around which the coil is wound is composed of a main magnetic flux portion 7 and a rounded portion 8. The main magnetic flux section 7
The shaded part 8' of the tooth part 6' on the adjacent side is the connecting part 9.
The connecting portion 9 has a recess 10 formed at an approximately intermediate position facing the slot 4, and the recess 10 increases the magnetic resistance. A magnetic wedge 11 is fitted into the opening 5, and the magnetic wedge 11 has a substantially tuft-like cross section and a semicircular shape in the middle so that the semicircular side wall forming the opening 5 coincides with the magnetic wedge 11. It is formed by a depression.

合する。 In the above configuration, when winding a coil around the stator core 2, the stator core 2
After inserting the coil into the slot 4 through the opening 5 provided in the yoke 1 and winding the coil around the teeth 6,
The magnetic wedge 11 is fitted into the opening 5 for inserting the coil.

特性が向上する。 Even when the end of the magnetic wedge 11 fitted into the coil insertion opening 5 protrudes outward from the coil insertion opening 5, the flat portion 3 is formed on the outer periphery of the yoke portion 1. The position of the opening 5 formed in the yoke part 1 is located substantially inside the imaginary line A of the circular outer circumference of the stator core 2, so that the end of the magnetic wedge 11 is located close to the stator core. Since the stator core 2 is prevented from protruding outward beyond the circular outer circumferential line of the stator core 2, when the stator core 2 is fitted into a motor frame etc., the magnetic wedge 11 does not come into contact with the frame and become an obstruction. , no excessive external force is applied to the yoke part 1, deformation of the stator core 2 is prevented, and the end of the magnetic wedge 11 can be extended close to the outer circumferential line of the stator core 2. The width of the wedge 11 can be increased, the magnetic flux density of the magnetic wedge 11 is reduced, and the characteristics are improved.

向上するという効果が発揮されるものである。 As described above, according to the present invention, the coil insertion opening provided in the yoke portion projects in a semicircular shape,
In addition, since it is formed so as to be located inside the outer circumferential line of the maximum diameter of the stator, the magnetic wedge fitted into the opening becomes a bundle shape, stably fixing the magnetic wedge, and reducing the width of the magnetic wedge. Even if it is made larger, it does not protrude beyond the outer periphery of the stator core, so the magnetic flux density of the magnetic wedge is reduced and the characteristics are improved.
