<P>PROBLEM TO BE SOLVED: To provide a configuration in which a converter for conversion between AC and DC is not required except for an inverter which drives a motor when a power is supplied to a wheel-side motor from a DC power source by way of an electromagnetic power feeding part. <P>SOLUTION: Coils 14L and 14R of electromagnetic power feeding parts 20L and 20R related to motors 4L and 4R are mutually connected through inverters 22L and 22R for performing output control while driving the motors 4L and 4R on corresponding sides respectively, and then, they are connected to a power source 21 through a common power feeding circuit 23. The power supplied from the power source 21 is converted to an AC by the inverters 22L and 22R, and then supplied respectively to the coils 14L and 14R of the electromagnetic power feeding parts 20L and 20R related to the motors 4L and 4R. The coils 14L and 14R generate a magnetic flux when an AC current is supplied, and the magnetic flux generated by the coils generates an AC electromotive force by interlinkage with the coils 16L and 16R related to the motors 4L and 4R. The AC electromotive force drives the motors 4L and 4R separately. <P>COPYRIGHT: (C)2013,JPO&INPIT |
