<P>PROBLEM TO BE SOLVED: To suggest a noncontacting feed device which first uniformizes the current of a feeder circuit, thereby reducing the power loss, and secondly decreases the cable resistance of the feeder circuit, thereby further reduced the power loss. <P>SOLUTION: The noncontacting feed device 9 is positioned closely in a noncontacting state with an air gap on the secondary side provided in a mobile from the primary side 10, based on a mutual induction action of an electromagnetic induction to supply an electric power. In a coil 3 on the primary side 10 and a coil on the secondary side, a plurality of insulating conductors are juxtaposed, and then, the conductor is wound plural times in a circular or square volute pattern. In a feeder circuit 21 on the primary side 10, in-series capacitors 7 for resonance synchronization are series-connected regarding the parallel coil 3, respectively. Furthermore, in the feeder circuit 21 on the primary side 10 and the feeder circuit on the secondary side, Litz wires of the cable on the I/O side of the coil 3 are paired and wired closely. <P>COPYRIGHT: (C)2010,JPO&INPIT |
