Abstract

PURPOSE:To obtain a coreless motor generating large torque with good efficiency by supporting with bearing a disk-shaped hollow coil around a disk shaped yoke rotatably and by arranging two sets of field magnets supplying magnetic flux in the opposite directions to both axial surfaces of said coil. CONSTITUTION:A hollow disk-shaped coil 13 is arranged on the outer peripheral part of disk-shaped yokes 8, 9 fixed on a bearing 6 part via a gap. The coil 13 is mounted on a rotary shaft 10 together with a commutator part 11, supported with bearings 6, 7, and is installed rotatably against the disk-shaped yokes 8, 9. Further, two sets of field magnets 3a, 3b, 4a, 4b that supply magnetic fluxes in the opposite directions on both axial sides of this disk-shaped coil 13 are placed facing to each other. In order to make the hollow disk-shaped coil, a projected part 9b is provided on one 9 of the yokes, and a bore part 8b is set on the other 8 of the yokes. And the projected part 9b and the bore part 8b are shifted, and the coil 13 is wound. Further, the yokes are shifted, and said projected part 9b and said bore part 8b are combined.
