摘要： A method and apparatus through which a moving shaft is stopped in a predetermined angular position. The shaft is driven at a maximum speed through an electrically driven motor. When the shaft is to be stopped at the predetermined angular position, the shaft is decoupled from the motor and an electromagnetic brake is applied. A regulating circuit controls the braking action so that it is dependent on a comparison of the actual output speed of the shaft and a desired input speed, as well as the comparison of a computed braking angle and the predetermined angular position to which the shaft is to be rotated. Position and speed sensors connected to the shaft provide signals representing the instantaneous output position and speed of the shaft.

摘要： Braking methods and the apparatus therefor are provided in accordance with the teachings of the present invention. According to one embodiment of this invention the rotation of a rotating device is detected and the angular disposition thereof is determined. The relative angular disposition of said rotating device is compared with the time of occurrence of a condition requiring the arrest of said rotating device. A brake signal adapted to produce hysteresis braking of the rotating device is generated in accordance with the comparison, whereby the velocity of said rotating device is rapidly reduced such that said rotating device halts at a desired angular disposition.

摘要： A single revolution crank system is provided for a DC motor, having a Hall effect sensing device employed as a position sensor. A bar magnet is attached to the DC motor shaft, with a magnetic Hall electrode device in the form of a Hall chip disposed adjacent the path of the bar magnet during its rotation on the shaft. A servo control loop is provided between the Hall effect device and the motor which is effective to substantially apply a constant voltage to the motor while the bar magnet has its one pole remotely disposed from the device, and with the one pole rotated to a position adjacent to the Hall effect device, an EMF is generated which is effective to reset a servo control flip-flop in the system to bring the motor velocity to zero. A mechanical detent is provided in the system to maintain the motor in the zero velocity position.

摘要： A control device generates, for each command cycle on the basis of machining line information expressing a plane machining line with a function displayed by a prescribed parameter and tangential line information showing a tangential line direction at respective positions of the machining line, a position command on a rotational axis and two linear axes with a position on the machining line obtained when the parameter is changed by a prescribed amount set as a machining position. The position command generated by the control device includes a command on a position of the rotational axis at which the tangential line at the machining position forms a prescribed angle set in advance with respect to any one of the linear axes and a command on the position of the two linear axes at which a tool is set at the machining position when the rotational axis is located at the position of the rotational axis.
