<P>PROBLEM TO BE SOLVED: To make it possible to output torque stably by reducing torque ripples without requiring prior measurement of the torque ripples when suppressing the torque ripples of a permanent magnet motor and even if a frequency of torque ripples which occurs to an output shaft is high. <P>SOLUTION: When even number of rotors of permanent magnet motors whose characteristics are the same are connected on the same shaft, the rotors are mounted by displacing a mounting angle so as to cause the torque ripples generated in each permanent magnet motor to have a phase difference canceling each other. Control amplifiers are installed which perform the torque control of each permanent magnet motor individually to distribute a torque command equally to each control amplifier. <P>COPYRIGHT: (C)2009,JPO&INPIT |
