    摘要： The rotary orientation of a motor is determined using a resolver signal derived from the rotary orientation. In particular, the resolver signal is fed exclusively to a single control system that is arranged both for triggering and for evaluating the resolver signal.

    摘要： A d.c. motor positions printing mechanisms. A circuit arrangement is provided in which a scanner disc, having peripheral slots, is arranged on the shaft of the motor and the slots are scanned by a scanner and counted in the positive direction and in the negative direction by a counter so that the position of the printing mechanism is determined. When the d.c. motor is decelerated and a generator voltage arises, the direction is determined by a rotation direction discriminator which evaluates the generator voltage and the zero transition thereof in the event of a change in the rotation direction of the d.c. motor. To control the direction of counting of the counter.

    摘要： The upper limit value and lower limit value of a control target value are alternately supplied to a single D/A converter in synchronism with a clock, an analog output from the D/A converter is compared with an output from a PBR serving as a position detector, and a motor is driven by the difference voltage, thereby positioning the control object. In this case, control of the moving direction and drive/stop of the motor is performed by a combination between the setting states of the upper and lower limit values and the polarity of the difference voltage, and the switching operation of the selector is stopped during a control operation, thereby making it possible to smoothly perform the control operation at a high speed. The control system can be digitized as a whole by detecting a position by an encoder, and integration of the system can be enhanced, thereby realizing a compact and stable control system.

    摘要： A control process and apparatus for positioning an electric motor provided with a rotation angle detector at a designated position positively at a high speed without being accompanied with hunting notwithstanding variation in the motor current and inertia of a load. The control process activated upon starting of the motor and ending at the stoppage of the motor at the designated position includes a first control region in which acceleration of the motor having been started is detected and subsequently a constant speed operation of the motor is effected at a maximum speed. A deceleration initiating time point is determined in dependence on the acceleration. A second control region is provided in which the motor is decelerated in accordance with a deceleration pattern determined in dependence on a rotation angle extending between a position corresponding to the deceleration initiating time point and the commanded stop position, and motor torque and inertia of load is detected at the deceleration initiating time point. During a third control region the motor is progressively decelerated by reducing correspondingly the gain of voltage (current) applied to the motor when the motor position approaches to the commanded stop position. The control process also includes a fourth control region in which, when the motor stops short of or beyond the commanded position, the duty ratio of voltage applied to the motor is progressively increased to thereby re-start the motor toward the commanded position, and a fifth control region in which the motor is held at the commanded stop position.
