The present invention provides a motor control method and a motor controller. In the motor control method and the motor controller according to the present invention, even when production tolerance of a motor or a control unit (ECU) or the change of an environment arises, abnormal sound of the motor due to the saturation of a motor applied voltage (Duty 100%) is not generated and a maximum output of the motor can be obtained and they may be applied to an electric power steering device. In a motor control method for controlling a motor by a motor driving voltage command value of a PWM, the motor control method includes the steps of calculating a degree of saturation of a motor driving voltage, and correcting a motor current command limit value based on the degree of saturation of the driving voltage.
