| 摘要 |
<p>The present invention relates to a motor controller of an air conditioner, including an inverter including a plurality of switching elements and adapted to convert input DC power into specific AC power, the inverter driving a motor including a stator coil and a rotor, output current detection means for detecting an output current flowing through the inverter, a parameter correction unit that corrects an inductance value of the motor based on the detected output current, and a microcomputer that outputs a switching control signal to drive switching elements within the inverter based on the corrected inductance value and the output current. Accordingly, accurate control can be performed by varying an inductance value, that is, a motor parameter according to an output current.</p> |
