摘要： A motor-driven dental device has a motor control that is responsive to a load placed upon the motor. More specifically, the invention relates to a dental device having motor that drives a tool, wherein the tool is activated or otherwise controlled in response to a load placed upon the motor through the tool, such as by touching the tool to a surface. The tool may also be controlled by the sustenance, over a predetermined time period, of an increase or decrease in motor current beyond a predetermined hysteresis current threshold. The motor may be an electric motor, a rotary electric motor, and air driven motor, an ultrasonic device or the like.

摘要： A motor speed control circuit including a voltage-dividing module, a first analog-to-digital converter, a second analog-to-digital converter and an operation module. The voltage-dividing module includes a first resistor unit and a second resistor unit. The first analog-to-digital converter receives a supply voltage and converts the supply voltage into a digital supply voltage. The second analog-to-digital converter receives a divided voltage generated by the voltage-dividing module, and converts the divided voltage into a digital divided voltage. The divided voltage is associated with a resistance ratio between the first resistor unit and the second resistor unit. The operation module receives the digital divided voltage and determines a motor speed curve according to the resistance ratio. The operation module generates a first pulse width modulation signal according to the motor speed curve and the digital supply voltage to drive a motor.

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。

摘要： An apparatus induces vibrations in a generator for effectively reducing vibrations of a vehicle engine and the vehicle body due to irregular combustion of the engine. The load torque of a generator fixed to the engine is changed to generate an angle moment on the body of the generator to cancel engine vibrations due to rough idling and suppress body vibrations due to the rough idling. Irregular combustion of the engine is detected from a change in the engine speed, and a voltage higher than the output voltage of the generator is than applied across the field winding to increase the field winding current and hence the load torque on the generator, which induces vibrations on the generator body. When the generator vibrations and vibrations due to irregular combustion are in inverse phase relationship to each other, they are cancelled.

摘要： A torque control unit rotates a motor machine having a motor element and a load element. The load element is coupled to the motor element via a rotational main shaft and driven to rotate by the motor element. Rotational acceleration at each rotation angle during one revolution of the rotational main shaft is detected and fed back. An electromagnetic torque of the motor element is controlled so that a difference between the electromagnetic torque of the motor element and a load torque of the load element may become zero at each rotation angle of the rotational main shaft.
