Abstract
An object of the present invention is to provide an inductive power supply system for an electric operation machine capable of readily increasing an allowable amount of a positional displacement between primary and secondary coils. An inductive power supply system for an electric operation machine having an electric storage device and a power receiver includes a power feeder provided with a pair of primary coils connected in series circuit to generate a magnetic dipole at energization. The power receiver has a secondary coil interlinkable to a magnetic flux generated by the primary coils and at the energization of the primary coils.
