PURPOSE:To obtain a highly safe heat from a cylindrical conductor by using a system in which a large number of permanent magnets are arranged on the periphery of a rotator in such a way that their polarities are alternately changed, a cylindrical conductor is fitted on the conductor in contact with the permanent magnets, and the rotator is turned. CONSTITUTION:A large number of permanent magnets 3a and 3b are attached in one or plural rows on the periphery of a disc rotator 1 to be driven by a motor, etc., in such a way that their polarities are alternately changed. And, a cylindrical conductor 4 is fitted on the disc rotator 1 in contact with these permanent magnets and the rotator 1 is turned, whereupon an alternating magnetism according to the revolving number is acted on the conductor 4 and thereby the conductor 4 is heated by eddy current. The quantity of heat produced there is equal to the output of the motor, and can also be increased by making the distance between the conductor 4 and the magnets 3a and 3b smaller. The heat is generated only when the rotator is turned, and therefore, a heat source device having a very high safeness can be obtained simply. |
