<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for motor control wherein even when any production tolerance is produced in the manufacture of a motor or a control unit (ECU) or the environment changes, there is no abnormal noise in the motor due to the saturation (duty 100%) of motor applied voltage, which are also applicable to electric power steering devices and make it possible to deliver the maximum output of the motor. <P>SOLUTION: A motor driving method is for driving a motor by a motor driving voltage command value for PWM. In this method, the degree of driving voltage saturation of the motor is computed, and a motor current command limit value is corrected based on the degree of driving voltage saturation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
