Title: Reverse driving method for wrist watch
Inventor: FURUHATA KATSUTOSHI
IPC: H02P8/00
Filed: 1990-07-10
Abstract: PURPOSE:To achieve an easy and stable driving method by varying one or both of the driving pulse width and driving voltage value to be applied on a step motor for the conditions of forward and reverse driving while furthermore inverting the output polarity. CONSTITUTION:Under normal operation, driving pulses having driving voltage of l.58V are outputted alternately and currents flow in the directions i1, i2 to produce same polarities in a rotor 2(having magnet diameter of 0.8mm-1.4mm) and a stator 1 (having inner diameter of 1.2mm-2.2mm) which thereby repel each other and sustain forward rotation. When a pulse (b) having driving voltage of 3V is outputted in the same direction as pulse (a) and the polarity is inverted, polarities of the stator 1 and the rotor 2 are inverted. At this time, S pole of the rotor attracts N pole of the stator 1 and N pole of the rotor 2 attracts S pole of the stator 1 and thereby the rotor 2 rotates reversely.
