PURPOSE:To obtain a large electromotive force from a small generator by providing a couple of magnetic poles consisting of an N pole and an S pole positioned at the internal circumferential faces that are opposite to each other in a double walled cylinder and inserting an armature coil into the double walled cylinder. CONSTITUTION:At the center of a shaft body 1 a shaft hole 2 is opened, and a disc 3 is provided at one end of the shaft, the disc 3 projects to fix a cylinder 4 that has magnetic poles 5a and 5b that consist respectively on N pole and S pole at radial positions of the internal surface and are arranged alternately. A rotating shaft 7 is fit into the shaft hole 2 of the shaft body 1 and pivoted in a cylindrical case 8, and a coil supporting cylinder 1 with magnetic permeability is provided, projecting from the side of the cylindrical case 8 toward the gap between the shaft body 1 and the cylinder 8, and this coil supporting cylinder is fitted with an armature coil 14. |
