Abstract
A motor driving apparatus includes a motor having a plurality of windings, a first inverter which is connected to a first end of each of the plurality of windings and drives the motor, a second inverter which is connected to a second end of each of the plurality of windings and selectively drives the motor according to a motor drive mode, and a controller which generates a current command for the motor according to a torque command and a voltage utilization rate control value, determines whether to perform linearization control for the current command based on a present counter magnetic flux of the motor and a switching reference counter magnetic flux for the motor drive mode, and adjusts the voltage utilization rate control value such that a value of the current command is linearized in a section in which the linearization control is performed.
