  • Induction heating apparatus and power generation system comprising the same
    Patent number: 9473049
    Abstract: An induction heating apparatus includes a rotor having a rotation shaft, and a stator having a heating portion disposed at a distance from the rotor. A coil that generates magnetic flux in a direction of the heating portion is provided in the rotor. The heating portion is formed of a composite material of a magnetic material and a conductive material, and has a structure in which a magnetic material portion and a conductive material portion are combined. When the coil is in a position opposed to the heating portion, a cross-sectional area of the magnetic material portion is smaller than an area of linkage of magnetic flux generated by the coil in the heating portion, and the conductive material portion is disposed to surround a periphery of the magnetic material portion. A flow passage in which the heating medium circulates is provided in the heating portion.
