Abstract
A motor driving control method for controlling a motor speed so that a speed measured value of a motor follows a speed command value is provided. The method includes driving the motor by repeating an on section where a torque is generated in the motor and an off section where a torque is not generated in the motor at a regular period, based on the speed command value, wherein the driving includes applying a phase voltage to only one of multiple phases of the motor in the on section by a pulse width modulation scheme.
