摘要： Eddy current attributed to leakage flux is suppressed, and the eddy current core loss is reduced. Teeth (61) are secured to a stator yoke (60). At least part (yoke insertion portions (81)) of the teeth (61) are inserted into insertion holes (75) made in the magnet-opposed surface of the stator yoke (60). The cross section S1 (see Fig. 6A), which is perpendicular to a line of magnetic force (B1) produced in a tooth (61) when a coil (62) is energized, of the yoke insertion portion (81) of the tooth (61) is larger than the cross section S2 (see Fig. 6B), which is perpendicular to the line of magnetic force (B1) in the in-coil location portion (82) of the tooth (61).

摘要： A rotating electrical apparatus with high productivity and maintenance easiness. A flat face (47) perpendicular to a rotation shaft is formed on a shaft portion (43) or on a portion where the size is reduced in a stepped manner. When magnetic poles (42) are bonded to a rotor (40), the magnitude of pressure applied to the poles with the flat face (47) used as a reference face or the distance from the flat face (47) is controlled using a jig etc., so that a gap can be controlled with excellent accuracy.
