Claim 8:
9. A method of controlling an inverter for driving a motor, the method comprising: controlling the inverter to apply a first input voltage for estimating resistance of a stator of the motor before applying a second input voltage for estimating a position of a rotor of the motor, in response to a start-up of driving of the motor; and controlling the driving of the motor based on the estimated resistance of the stator according to a result of applying the first input voltage, wherein the first input voltage includes a third input voltage and a fourth input voltage, a maximum value of the third input voltage is different than a maximum value of the fourth input voltage, and angles of composite magnetic fluxes of the motor generated due to the third input voltage and the fourth input voltage are the same and wherein the controlling of the inverter includes controlling the inverter to apply the fourth input voltage when a time, which exceeds a threshold time, has passed from a point at which a response current of the third input voltage is 0 amperes.
