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.

摘要: A vehicular steering system can suppress steering of steerable road wheels in a direction not intended by a driver. A steering mechanism steers the steerable road wheels in accordance with a steering wheel and an auxiliary steering angle superposition mechanism. A calculation section calculates a target auxiliary steering angle corresponding to a steering wheel angle of the steering wheel. A detection section accurately detects the auxiliary steering angle based on detection signals of a rotation angle sensor that detects a rotation angle of a rotational member. A driving section controls the auxiliary steering angle superposition mechanism so as to make the auxiliary steering angle coincide with the target auxiliary steering angle. An auxiliary steering angle detection abnormality monitoring section detects abnormality of the auxiliary steering angle detection section. The auxiliary steering angle detection section includes a counting section that counts the number of revolutions per minute of the rotational member.

摘要: A three way electromagnetic valve has a plunger provided with a small-diameter section, the diameter of which is smaller than the diameter of a plunger seat, so as to increase the sectional area of a fluid passage running between an output port and a discharge port. The inner wall surface of a ball holding section is provided with ball guides for guiding a ball. The diameter of the ball holding section is made larger than the diameter of the ball in order to secure the flow rate of a fluid in the ball holding section.
