摘要： An electromechanical valve positioning apparatus having a control circuit for driving a stepping motor to position a valve regulating flow of a medium within a conduit in response to a pair of input signals indicating respectively whether the valve should be opened or closed. The control circuit contains a pair of oscillating driving circuits for driving the motor in opposite directions, each driving circuit being operated in response to a respective input signal. Each driving circuit has an associated timing circuit for disabling it after its respective input signal has occurred for a predetermined period so that the motor is not driven for an indefinite period after the valve has reached an extreme or seated position. Preferably, each timing circuit includes a timing capacitor which is charged in response to its respective input signal and a unijunction transistor which is connected to the capacitor for firing a pulse when the capacitor has been charged to a predetermined level. Upon firing, each unijunction transistor gates an SCR for terminating operation of the associated driving circuit. The SCR remains in this state preventing driving of the motor until the other input signal is received indicating that the motor is to be driven in its other direction.

摘要： Controlling a stepper motor. A stepper motor is driven towards an index position. An attempt is made to stop the stepper motor on the index position in a fashion that would ordinarily cause the stepper motor to ring at the index position. Characteristics of one or more subsequent pulses that would counteract the ringing are determined. The one or more determined subsequent pulses are issued to the stepper motor.

摘要： A process for reducing the strength of an uncontrolled movement of a pointer driven by a stepper motor and abutting against a mechanical stop means when the stepper motor is switched off. Prior to the switch-off operation, the field strength of the magnetic field of the stepper motor is lowered, or the pointer is moved away from the stop means by a specified compensating angle of rotation. Alternatively, following the switch-off operation, the stepper motor is switched on again at least one time following a specified time span for a specified switch-on time span.

摘要： A stepping motor controller for controlling a stepping motor, includes: a motor driver; and a driver control unit. The motor driver includes: an excitation phase control unit; and a drive unit. The driver control unit includes: a motor driver power control unit; a drive control unit; a clock signal output unit; and an excitation phase storing unit. The excitation phase storing unit acquires an excitation phase at a time when the motor driver power control unit stops supplying electricity to the motor driver, and stores the acquired excitation phase as a suspension excitation phase. When the motor driver power control unit resumes supplying electricity to the motor driver, the drive control unit instructs the drive unit to continue to halt the supply of the drive current until the excitation phase signal is updated, in response to each pulse of the clock signal, to an excitation phase signal specifying the suspension excitation phase, and instructs the drive unit to supply the drive current after the excitation phase signal is updated to reach the excitation phase signal specifying the suspension excitation phase.

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.
