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 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.
