摘要： A driver circuit for a stepping motor having a coil, a stator and a rotor receives pulse signals from a pulse signal generator to rotationally drive the rotor. A rotation detection circuit comprises switching circuitry switchable between a high impedance loop formed of the coil and a high impedance element and a low impedance loop formed of the coil and a low impedance element, and means for detecting the voltage induced in the coil. After a pulse signal is applied to the stepping motor, the switching circuitry forms the high impedance loop and the detecting means compares the voltage developed across the high impedance element with a predetermined voltage to thereby detect the rotation and non-rotation states of the rotor.

摘要： An electronic timepiece has a stepping motor comprised of a stator, rotor and driving coil. A wave shaping circuit produces normal driving pulses and correction driving pulses having a longer pulse width than the normal driving pulses. A rotor rotation detection device detects rotation and non-rotation of the rotor after normal driving pulses are applied to the driving coil and in response to detection of a non-rotation condition, a correction driving pulse is applied to the driving coil. A magnetic field detection device detects the presence and absence of an external alternating magnetic field and in response to detection of a magnetic field, a driving pulse of longer pulse width than the correction driving pulses is applied to the driving coil to effect rotor rotation. The magnetic field detection device operates before the normal driving pulses are applied to the driving coil so that in the event of detection of a magnetic field, a driving pulse of sufficiently long pulse width will be applied to the driving coil to effect rotor rotation. In response to detection of an external alternating magnetic field by the magnetic field detection device, operation of the rotor rotation detection device is inhibited thereby conserving power and preventing mis-operation of the stepping motor.

摘要： An electronic timepiece of the type having a frequency dividing circuit, and a drive circuit for driving a motor having a rotor, a stator and a driving coil, is provided with a magnetic field detection device comprised of a low impedance closed loop including a low resistance element and the driving coil and a high impedance closed loop including a high resistance element and the driving coil. The driving coil develops an induced voltage when placed in an external alternating magnetic field and also functions to drive the rotor. The strength of the alternating magnetic field is measured by the voltage level developed across the high resistance element and the measuring sensitivity is improved by alternately switching between the low impedance closed loop and the high impedance closed loop. In response to the detection output of the magnetic field detection device, the effective power applied to the driving coil is increased so that the motor performance is not adversely affected by the external alternating magnetic field.

摘要： An electronic timepiece including a dividing circuit for developing different output pulse signals having different respective pulse repetition rates, a stepping motor and a drive circuit responsive to control signals for driving the stepping motor at a normal rate and for applying a correction pulse to the stepping motor according to the control signals. A pulse combining circuit combines the different output pulse signals from the dividing circuit for generating control signals and for applying the control signals to the drive circuit. The pulse combining circuit normally generates a control signal effective to drive the stepping motor at a normal rate, and the pulse combining circuit is responsive to a correction signal to control the drive circuit to apply a corrective pulse to the stepping motor. A detection circuit detects rotation and non-rotation of the stepping motor rotor and generates a detection voltage signal indicative of the state of rotation of the rotor. A voltage comparing circuit compares the detection voltage signal with a standard voltage value and applies a correction signal to the pulse combining circuit when non-rotation of the stepping rotor is detected after a drive pulse is applied to the stepping motor.

摘要： An electronic timepiece includes a stepping motor having a coil and a rotor. Circuitry is provided for generating and applying alternating pulses to the motor coil to effect forward stepwise rotation of the motor rotor in a forward direction and for generating and applying alternating pulses to the motor coil to effect reverse stepwise rotation of the motor rotor in a reverse direction. The reverse rotation is achieved by sets of three alternating pulses with the first pulse of each set effecting incremental angular movement of the motor rotor in the forward direction followed by the second and third pulses which effect greater icremental angular movement of the motor rotor in the reverse direction to thereby obtain for each pulse set a net angular movement of the motor rotor in the reverse direction.

摘要： An analog electronic timepiece has a stepping motor for rotationally driving the timepiece hands. The motor is driven by normal driving pulses during normal load conditions and in the event the normal driving pulses are unable to effect rotation of the motor, correction driving pulses of longer pulse width than the normal driving pulses are used. A detection circuit detects whether or not the motor has rotated by switching a resistance element in series with the motor drive coil after the application of each normal driving pulse. Rotation and non-rotation of the motor is determined by measuring the voltage across the resistance element and comparing the measured voltage with a reference voltage.
