WE investigated to apply the bipolar flat motor for driving hands of an analog quartz watch to a vibration alarm motor of a watch. It is indispensable to be able to rotate the rotor with eccentric weight stably and high-speedly in order to take big vibration out of a vibration alarm motor. Then, we introduced a new drive method by which a motor can rotate self-encouragingly. The new drive method is a method that drives a motor synchronizing with the rotor position signal which is generated by a rotor position detection coil. By the new drive metod, the vibration alarm motor, nevertheless of small size and low power-consumption, is able to generate a big vibration force of about 20 gf.
