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 small-sized and inexpensive electric motor in which connection of a stator coil is easy, the connecting portion occupies a small space, and stable torque characteristics are obtained by making electric resistance uniform. A coil bobbin is mounted on a magnetic pole of a stator core, and a stator coil is fitted. A lead wire is led to an external diameter side of one end of the stator core. A connecting conductor holder with a common coil-connecting conductor, connecting conductors for each phase and a through hole is mounted on an end of a coil bobbin. The common coil-connecting conductor has connecting terminals projecting in radial directions, and the connecting conductors for each phase have such a cross-sectional area as to equalize electric resistance of each phase after connecting the stator coil. The through hole is formed to allow a bearing-housing portion to be inserted.
