Abstract

The invention concerns a method for controlling a bidirectional stepping motor having two windings and three pole faces. The invention comprises applying current pulses alternately to only one of the motor windings to cause it to rotate in one direction and to only the other of the motor windings to cause it to rotate in the other direction. The invention is used for controlling bidirectional motors which are employed in particular in timepieces.
