Abstract:
An aspect of the disclosed invention calculates a value of an inductance of a synchronous motor whose characteristic is unclear while suppressing a failure of the synchronous motor. A motor driving device according to an embodiment of the disclosed invention comprises: a motor; an inverter for supplying an alternating voltage to the motor; a current meter for measuring an introduced current flowing through the motor on the basis of the alternating voltage; and a control unit for controlling the inverter to change the size of the alternating voltage in stages, and calculating an inductance of the motor on the basis of the introduced current measured by the current meter.

Claim (Index 8):
A method of controlling a motor driving device including a motor and an inverter configured to control the motor, the method comprising:\n gradually changing a magnitude of an alternating current (AC) voltage; suppling, by the inverter, the AC voltage to the motor; measuring an introduced current flowing in the motor on the basis of the changed AC voltage; and calculating an inductance of the motor on the basis of the measured introduced current.
