摘要： In an actuator, an electric power supply to a position-detecting detector for an object to be driven can be carried out in a timely manner during a power failure to thereby suppress an electric power consumption in the position-detecting detector, whereby duration time of a power-failure compensation battery can be prolonged, and a variety of detectors can be selected and utilized without limitation in accordance with a use environment and usefulness. During the power failure, a switching means 40 establishes a linking state in which an input shaft 11 of a reduction mechanism 10 and a manual inputting means 30 are linked to each other. When the linking state is detected by a detecting means, an electric power is fed from a battery 80 to a rotation detector by a control section 70, so that the control section 70 can obtain a displacement of the object to be driven, based on a signal output from the rotation detector. In a state in which the input shaft 11 of the reduction mechanism 10 can be manually rotated, the electric power is fed to the rotation detector. Thus, a useless consumption of the electric power of the battery 80 can be suppressed, and it is possible to suitably obtain the displacement of the object to be driven without an interruption even if the power failure happens.

摘要： There is provided an actuator in which an worm is rotationally driven by an electric motor, and in which an angular velocity of the electric motor is repeatedly fluctuated so that the rotation of the worm is carried out as if the worm is oscillated in the rotational direction thereof, to thereby decrease contact friction of the worm against a worm wheel, resulting in an improvement of an efficiency of force transmission of the worm gear mechanism.Although the electric motor 20 is inherently controlled so that an output shaft 21 thereof is rotated at a target velocity based on a velocity command, a drive control section 40 controls the angular velocity of the output shaft 41 so as to be repeatedly increased and decreased with respect to the target velocity so that the angular velocity of the worm 11 is finely fluctuated, and thus the fluctuation of the angular velocity may be regarded as a fine general-oscillation of the rotating worm 11 in the rotational direction, whereby friction between the gear faces of the worm 11 and the gear faces of the worm wheel 12 can be decreased, resulting in an improvement of the efficiency of force transmission of the worm gear, and in increase in a driving force and a torque value to be transmitted to an object to be driven by the actuator.
摘要翻译：提供了一种致动器，其中蜗杆由电动机旋转驱动，并且其中电动机的角速度反复波动，使得蜗杆的旋转如同蜗杆沿旋转方向振动地进行从而减小蜗杆与蜗轮的接触摩擦，从而提高蜗轮传动机构的力传递效率。虽然电动机20被固有地控制，使得其输出轴21基于速度指令以目标速度旋转，但驱动控制部分40控制输出轴41的角速度，以便随着相对于目标速度，使得蜗杆11的角速度微小地波动，因此角速度的波动可以被认为是旋转蜗杆11沿旋转方向的微小的一般振荡，由此齿轮之间的摩擦可以减小蜗杆11的表面和蜗轮12的齿轮面，从而提高蜗轮的力传递效率，并且增加驱动力和扭矩值以传递给物体由致动器驱动。
