摘要： A rotation angle detector includes a stator core (2) comprised of a plurality of core sheets (4) each having plural core members (4a) each including a tooth and a yoke portion (5a, . . . , 5h, 4b) disposed in a strip-like array with adjacent core members being coupled to one another by coupling means (4d) at yoke end portion. The core member is laminated. The stator core is shaped into an annular form by bending the core members at coupled portions so that the tooth portions extend centrally while capable of extending substantially linearly upon expansion thereof. An exciting winding (8) and output windings (9, 10) of n phases are wound on the tooth portions. A rotor core (3) is disposed rotatably relative to the stator core such that gap permeance between the rotor core and the tooth portions changes sinusoidally as a function of the rotation angle.

摘要： A method of forming an armature core for an electric rotating machine is disclosed. The band-shaped metal sheet for forming a core sheet has a multiplicity of grooves formed along a longitudinal edge which defines the inner peripheral edge of a core sheet when the metal sheet is formed into an annular shape. The metal sheet is wound around a mandrel having projections thereon so that the grooves engage with the projections, respectively. Then, the grooves which open at the inner edge of the disk are deformed so as to be closed, for example, by ironing the inner peripheral edge of the disk. Thus, the inner surface of the core sheet for press-fitting an armature rotary shaft is formed into a continuous surface with no groove opening present therein. Accordingly, when the armature rotary shaft is press-fitted into the shaft, the core sheet contacts the shaft around the complete inner circumference of the bore, thus ensuring firm press-fitting of the shaft.
