摘要： A stepping motor driving apparatus for a camera having a 1-2 phase excitation type stepping motor which is driven by a 1-2 phase excitation in response to a drive signal includes a drive control device for stopping the stepping motor at a 1-phase excitation position by de-energizing the stepping motor at the 1-phase excitation position and for stopping the stepping motor at a 2-phase excitation position while maintaining the excitation in a high precision drive control in which the stepping motor is driven at high precision. The drive control device stops the stepping motor by de-energizing the stepping motor always at the 1-phase excitation position in a normal drive control in which no precise drive control of the stepping motor is needed.

摘要： A pulse motor control device comprises, as additional component parts, a power-off detecting circuit, and a turning-off circuit. The power-off detecting circuit detects, when a driving switch is turned off, a dropping of a voltage supplied to a driving circuit and outputs a power-off detection signal. The turning-off circuit includes diodes and a control resistor. The diodes are connected respectively to control terminals of all driving transistors of the driving circuit. When the control transistor is turned on in response to the power-off detection signal, voltages of control terminals of the driving transistors are dropped to the ground level through the diodes, thereby turning off the driving transistors.

摘要： A stepper motor controller which can control the motor to stop rapidly and with minimum overshoot and oscillation at a selected position by turning on and off one or several coils in a binary fashion to force the motor to conform to a predetermined position/velocity profile, resulting in the motor velocity and the position deviation from the null point to converge to zero at the selected null point. An encoder continuously generates current position and velocity data, a comparator compares the current velocity and position to a predetermined velocity/position profile to produce a binary output, and one or several motor coils are energized to drive the current motor velocity toward the predetermined value.

摘要： A disc rotatable with the motor shaft has circumferentially equally spaced slots formed therethrough. A light source and receiver assembly are operatively arranged relative to the slots to produce pulses representing a predetermined angular displacement of the motor shaft determined by the width of the slots as the motor shaft rotates. The duration of the pulses decreases as the motor shaft speed increases. A multivibrator is triggered by the leading edges of the pulses to generate reference pulses of a predetermined duration. The motor phases are excited in a normal sequence as long as the duration of the pulses is longer than the duration of the reference pulses. When the pulse duration becomes less than the reference pulse duration, coincidence sensing means alter the phase excitation during the times between the termination of the pulses and the termination of the respective reference pulses to apply a torque to the motor shaft in such a manner as to prevent the motor shaft from accelerating further. The torque may be a low positive torque which is insufficient to overcome the frictional forces in the motor control system, a zero torque produced by de-energizing all of the motor phases or a reverse torque. The result is that the motor shaft speed is prevented from exceeding a predetermined value.

摘要： A closed-loop control system for a step motor which is started by a pulse from an external source, and then driven by feedback pulses from a transducer connected to the motor output. Each time the motor advances a step, the transducer generates a feedback pulse at a reference switching angle which determines the torque output of the motor and, therefore, the motor speed for any given load. An adjustable time delay is provided in the feedback loop for adjusting the effective switching angle at which the feedback pulses are applied to the drive unit of the motor, by delaying the feedback pulses. To automatically stabilize the motor at a selected speed, a signal representing the desired speed is compared with the actual motor speed, and an error signal is generated representing any difference between the actual and desired speeds. This error signal is then used to automatically select the magnitude of the time delay introduced into the feedback loop. The error signal may represent only the direction of the error, and the time delay means adjusted by a fixed unit of time after each motor step in the direction required to return the actual motor speed toward the desired motor speed. Alternatively, the error signal may represent both the magnitude and direction of the error, and the time delay adjusted in proportion to the magnitude of the error and in the direction required to return the actual motor speed to the desired motor speed. The system also includes means for automatically stopping the motor after a predetermined number of steps, and means for generating decelerating and/or damping pulses after termination of the feedback pulses.
摘要翻译： 一种用于步进电动机的闭环控制系统，其通过来自外部源的脉冲启动，然后由连接到电动机输出的换能器的反馈脉冲驱动。 每当电机进行一步时，换能器以参考切换角度产生反馈脉冲，该参考切换角决定了电机的转矩输出，因此决定了任何给定负载的电机转速。 在反馈回路中提供可调节的时间延迟，用于通过延迟反馈脉冲来调整反馈脉冲施加到电机的驱动单元的有效切换角度。 为了以选定的速度自动稳定电动机，将表示期望速度的信号与实际电动机速度进行比较，并产生表示实际速度和期望速度之间的任何差异的误差信号。 然后，该误差信号用于自动选择引入到反馈回路中的时间延迟的幅度。 误差信号可以仅表示误差的方向，并且时间延迟装置在每个电动机阶跃之后以固定的时间单位调整，以使实际电动机速度朝向期望的电动机速度返回所需的方向。 或者，误差信号可以表示误差的大小和方向，并且时间延迟与误差的大小和将实际电动机速度返回到期望的电动机速度所需的方向成比例地调整。 该系统还包括用于在预定数量的步骤之后自动停止电机的装置，以及用于在反馈脉冲终止之后产生减速和/或阻尼脉冲的装置。
