A motor driving control apparatus for driving a motor repeats alternately the supply of current to the motor coil during the exciting period and the non-supply of current to the motor coil during the non-exciting period. For this apparatus, a short period is set to enable each of the feeding points of the motor coil to be short-circuited totally during the non-exciting period, and an open period is set to enable each of the feeding points to be totally in the open status during the open period.
