摘要： A motor control apparatus includes a steering column having inserted therein a steering shaft to which steering torque is transmitted, a reduction gear box coupled to the steering shaft, and an electric motor that transmits a steering assisting force to the steering shaft via a reduction mechanism in the reduction gear box. The electric motor and its control unit including a control board mounted with a control circuit, are provided side by side in the reduction gear box. A connection terminal of the electric motor is electrically connected to the control unit directly. This minimizes a connection distance between the control unit and the electric motor.

摘要： A linear motor includes a row of permanent magnets fixed at a position above a stator, and a plurality of magnetic pole members fixed at a position below a movable member. The row of permanent magnets is formed from N poles and S poles alternately arranged at given intervals. The plurality of magnetic pole members extend toward the row of permanent magnets and in a vertical direction and have the same height. The extremities of the magnetic pole members oppose the row of permanent magnets via an air gap. The magnetic pole members are coated with insulators, and a former-wound coil is fitted around the insulator. The part of the magnetic pole member coated with the insulator, except for the extremity thereof, is made thin by the amount corresponding to the thickness of the insulator.

摘要： A sealed actuator includes a motor stator having rotation-drive magnetic poles; a motor rotor arranged so as to confront magnetic pole surfaces of the motor stator while interposing a small distance therebetween and rotatably supported through roller bearings; and displacement detecting means for measuring displacement of the motor rotor. A partition wall made of a nonmagnetic metal is disposed in a clearance between the motor stator and the motor rotor, so that the inner space where the motor stator is disposed is hermetically covered. The bearings are disposed at both sides of the partition wall in the axial direction so that the load applied to the bearings are directly received by a housing. At least a part of the partition wall is reinforced by reinforcing members and a mold agent is charged into the space on the motor stator side.

摘要： Since an abnormality is judged by executing a square calculating process with respect to sin θ and cos θ for detecting an abnormality in an angular resolver, a processing time is elongated, and a burden to a CPU is great. Since the invention prepares a map which can judge whether the combination of sin θ and cos θ is normal or abnormal, and judges by mapping the combination of the detected sin θ and cos θ, a process can be easily executed, a processing speed is high, and a burden to the CPU can be reduced. Further, an assist can be maintained by controlling a motor by a rectangular wave current by detecting a rotation angle signal at low resolution level, such as Hall sensors arranged around the motor.
