Provided is an inverter. The inverter according to one embodiment of the present invention includes a back-stepping control unit which receives current information and torque information from a motor, receives information about a rotor speed from an encoder, and provides the location information of a rotor, and a current controller which supplies an output voltage to the motor by using the location information of the rotor supplied from the back-stepping control unit. The back-stepping control unit provides the corrected location information of the rotor by using the torque information supplied from the motor in the case external disturbance is generated in the location of the rotor of the motor. |
