ABSTRACT:
A small generator with collective multiple magnetic poles includes a magnet, multiple magnetic poles arranged in an annular shape and facing to the magnet, an annular iron core having its outer circumference combined with the multiple magnetic poles spaced apart and equidistantly. The iron core forms magnetic circuits for the magnetic poles so as to let magnetic lines of force to pass through. A sheet-shaped coil is combined on each magnetic pole so that when the magnet is rotated around the iron core with the magnetic poles, the sheet-shaped coil may generate alternate electric current. The sheet-shaped coils are quickly made by mechanical process, with magnetic wires requited for the coils reduced a lot.
