Claim 2:
3. The motor drive device of claim 2, wherein the controller comprises:
a current command map configured to generate current commands based on preset demand output of the motor;
a current control part configured to compare the generated current commands with a detected value of a current supplied to the motor and to generate voltage commands of the motor in order to reduce a difference obtained by the comparison;
a first duty generation part configured to generate voltage commands of the first inverter by multiplying each of the voltage commands of the motor by 1/√{square root over (3)}, and to respectively convert the voltage commands of the first inverter into the phase voltage commands of the first inverter; and
a second duty generation part configured to generate voltage commands of the second inverter from the voltage commands of the motor, and to respectively convert the voltage commands of the second inverter into the phase voltage commands of the second inverter.
