<P>PROBLEM TO BE SOLVED: To provide a motor driving system capable of restraining a resonance phenomenon in which axial torsional vibration occurs to a power generator, the vibration is transmitted to an inverter for driving a motor as a power generator terminal voltage change to change a motor terminal voltage and vibrate a motor shaft, and the vibration further vibrates a power generator shaft, without depending on a special control. <P>SOLUTION: A motor driving system comprises a prime mover, a power generator for generating power by driving the prime mover, a converter for converting the power generated by the power generator into power with a desired frequency, a motor driven by the power supplied from the converter, and a driven device driven by the motor. A value of an axis resonance frequency of the power generator shaft transmitting a driving force of the prime mover to the power generator is made different from that of an axis resonance frequency of the motor shaft transmitting a driving force of the motor to the driven device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
