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 14):
The method of  claim 11 , wherein the calculating includes:\n storing a d-axis inductance calculated on the basis of the AC voltage as a first result value; storing a d-axis inductance calculated according to the gradually changed AC voltage as a second result value; and comparing the first result value and the second result value and determining the d-axis inductance.
