Space-division multiple power feeding and collecting apparatus

A phase division multiple power feeding apparatus that feeds electric power to a moving body using magnetic induction which comprises

• A power feeding core which have multiple magnetic poles arranged at regular intervals along the traveling direction of a moving body,
• Three feeding lines in which along the traveling direction of a moving body, electric current of phase difference of 120 degree flows, and an inverter which controls electric current flowing in each of said feeding lines;
• Each of feeding lines is arranged so that the N and S poles are alternately generated at every 3 out of a certain number of magnetic poles (‘magnetic pole group’), and the N-S pole pairs generated by each of feeding lines are not overlapped each other.

A time division multiple power feeding apparatus that feeds electric power to an electric vehicle using magnetic induction of the present invention which comprises

• A power feeding core which has multiple magnetic poles arranged at regular intervals along the traveling direction of a moving body,
• A certain number (‘b’) of feeding line pairs in which along the traveling direction of a moving body, electric current flows countercurrent to the traveling direction of a moving body, and an inverter which controls electric current flowing in each of said feeding line pairs in which electric current flows in different time zones;
• Each of feeding line pairs is arranged so that the N and S poles are alternately generated at every b magnetic poles.

A power collecting apparatus which collects electric power from the space division multiple power feeding apparatus which feeds electric power to a moving body using magnetic induction which comprises

• A power collecting core which is installed at the bottom of a moving body with space from the power feeding apparatus, and
• A power collecting coil which is wound around said power collecting core so that electric current induced by the power feeding apparatus may flow, and the power collecting coil comprises more than two pairs so as to multiple collect electric power.
