Claim 2:
3. The apparatus of claim 2, wherein the resonance suppression control part comprises:
a basic data storage part configured to store information about a high-frequency gain limit value, a maximum value of interlinkage magnetic flux by an equivalent permanent magnet, a natural frequency of the servo motor part, an angular velocity at an operation point, a direct current gain of a resonance suppression controller, inductance of a winding of a stator of the servo motor part, the number of pole pairs of the servo motor part, resistance of a winding of a stator of the servo motor part, and inertia moment of force of the rotor of the servo motor part;
a second servo motor feedback information storage part configured to store feedback information about a position and a speed of the second servo motor which is generated when the second servo motor and the first servo motor operate in parallel;
a calculation part configured to calculate an invalid torque value to be transmitted to the power conversion part based on data stored in the basic data storage part and feedback information of the first servo motor and the second servo motor stored in the second servo motor feedback information storage part and the first servo motor feedback information storage part; and
an invalid torque command part configured to output an invalid torque signal to transmit the calculated invalid torque value to the power conversion part when the invalid torque value calculated by the calculation part is not 0.
