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.
