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 7):
The motor driving device of  claim 1 , wherein:\n the motor includes a rotor including a permanent magnet and a stator; and the controller controls the rotor to determine a position of the rotor and controls the inverter to gradually change the AC voltage.
