摘要: In a circuit for the actuation of a stepping motor for battery-operated instruments, in particular watches, the length of motor drive pulses is altered for the purpose of saving energy. In the process, different loads on the stepping motor and variable battery voltages are taken into consideration. This feature is accomplished by measuring a signal proportional to the current flowing through the field coil of the stepping motor and interrupting the drive pulse to the motor when a predetermined change occurs in the signal. The drive pulses are further limited as to both minimum and maximum length. Advantageously, the stepping motor is actuated and the signal processed by means of a digital circuit technology, in order to provide for complete integration of the circuit.
