Abstract
A motor driving apparatus is a pulse generation circuit applying a drive pulse for rotating a rotor to a two stepping motor including the rotor magnetized in two poles and a stator in which a two-phase coil is wound around a yoke. The drive pulse is constituted of a drive pulse P1 and a drive pulse P2. The pulse generation circuit applies the drive pulse P1 having a stable stationary position at which a rotor rotation angle from a reference position is 90 degrees or less and applies the drive pulse P2 having a stable stationary position at which the rotor rotation angle from the reference position is 90 degrees or more continuously to the application of the drive pulse P1.
