Abstract
A motor driving apparatus includes a motor having a plurality of windings, a dual inverter including a first inverter connected to first ends of the plurality of windings and a second inverter connected to second ends of the plurality of windings and configured to drive the motor through at least one of the first inverter or the second inverter according to a motor driving mode, and a controller configured to determine whether flux weakening control is performed according to an available voltage level of the dual inverter when a switching condition of the motor driving mode is satisfied and to perform the flux weakening control by linearly adjusting an output voltage level of the dual inverter for a preset time interval for which the flux weakening control is performed.
