Abstract
This invention is concerned with an electronic damper for a pulse motor wherein at the time of oscillation or rotation of a rotor in a pulse motor of a 1-phase excitation method having at least one pair of windings wound up to generate electromotive forces with the opposite polarities, a switching element is actuated in synchronization with completion of pulse driving the pulse motor, said one pair of windings are connected through a capacitor and the rotor can be brought to a standstill immediately by neutralizing the electromotive forces led up to each winding.
