<P>PROBLEM TO BE SOLVED: To provide a drive method of a rotating electric machine that can increase motor output, while lowering the voltage peak, improve the torque of each rotor in particular, and thereby expand the drive range of a motor. <P>SOLUTION: In the drive method for driving the rotating electric machine having two coaxial rotors outside and inside a stator, a voltage applied for driving is made to contain harmonic components, in order to realize two voltage amplitudes for individually driving the two rotors. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
