Title:
INDUCTION HEATING ROLLER DEVICE
Document Type and Number:
Japanese Patent JP2002164159
Kind Code:
A
Abstract:

To provide an induction heating roller device prevented from the lowering of the temperature at a roller surface caused by the potential difference between end parts of induction coils divided into a plurality.

Induction coils A, B and C for the induction heating system, divided into a plurality, successively installed inside a cavity of rotating roller in the direction of roller axis, are excited by an single phase power source U, V. An identical potential is impressed to a winding end part of the induction coil A, and to a winding starting part of the induction coil B adjacent to the induction coil A, and the induction coil A is wound forward and the induction coil B is wound reverse so as to make the direction of fluxes Φa, Φb identical, and the potential ant the way of winding of the induction coil C adjacent to the induction coil B is set with the same way as the above. This is also applicable when connecting the induction coils divided into plurality to a three-phase power source.
