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： Disclosed are a backlash vibration reduction apparatus and method capable of sufficiently performing gear alignment even when torque is increased while a vehicle is driven within a low torque range, thereby minimizing rough vibration due to backlash. The backlash vibration reduction apparatus includes a correction determination unit configured to determine whether it is necessary to correct a torque gradient to be applied for an increase to target torque in the state in which the current torque of a vehicle is retained within a predetermined low torque range and a torque gradient correction unit configured to determine a corrected torque gradient in which a torque increase rate per hour is reduced and a torque increase time period is extended by multiplying a correction factor by a first torque gradient as a torque gradient that increases the current torque upon determining that it is necessary to correct the torque gradient.

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： A safety garage door apparatus includes a garage door, two tracks, a controller, a linking device and a detecting device. Two tracks are installed on two sides of the garage door, respectively. The controller includes a motor, a driving device connected to the motor, and a microprocessor. The linking device includes a rail, a rack slidably mounted in the rail, and a linkage with one end connected to the rack and the other end connected to the garage door. The rack is connected with the driving device. The detecting device is mounted in the controller to continually detect a location of the rack so that a moving speed of the rack is determined by the microprocessor to compare with a predetermined rate to determined whether an operation of opening or closing the garage door needs to be stopped or reversed, or a maintenance of the garage door apparatus is needed.
