ABSTRACT:
Pulse motor driving system for use in a timepiece. The driving system has a single phase coil and permanent rotor which are stepped in a forward direction by a forward rotation driving voltage. The voltage is composed of a plurality of pulses having the same polarity. Provision is made for a control circuit connected between a frequency divider and pulse motor driving circuit. The control circuit applies a plurality of driving voltage pulses for rotating the rotor of the pulse motor in the reverse direction. The control circuit also can provide accelerated pulses to the movement of the rotor in the reverse direction thereby stepping the rotor in the reverse direction. This enables the lag of gaining hands thereby correcting the time display in preciseness.
