PURPOSE:To increase both an output torque and a rotating speed of an incremental stepping motor of a member of an automatic machine by guiding magnetic energy generated when an armature coil is deenergized to an armature coil to be conducted next. CONSTITUTION:Energization of series or parallel connectors K, L of armature coils 16a, 16b and 17a, 17b is controlled by an electric pulse to terminals 12a, 12b and 12c, 12d of an incremental stepping motor of an automatic machine. When transistors 7a, 7b of the coil K are deenergized, return of stored magnetic energy to a power source is interrupted by a diode 9a. Accordingly, in this case, it is fed as a high voltage to the coil K through transistors 7c, 7d conducted simultaneously. that is, since the elimination and storage of the magnetic energy of the coil are quickly completed, a high speed stepping is performed. |
