ABSTRACT:
A sheet coil motor is configured such that a plurality of coil units are attached to a circuit substrate at a predetermined interval, the interval separating the coil units are regular. Each of the plurality of coil units includes a plurality of coils and has a shape of a sector. Accordingly, the sheet coil motor can be made thin, the number of driving sheet coils can be reduced, and the production cost can be reduced. A method of fabricating the sheet coil motor includes the steps of printing, on a sheet base, a plurality of sheet coil units, in which units a plurality of sector-shaped coils are provided, such that the coil units lie in alternately opposite directions, cutting out the sheet coil units from the sheet base, attaching sheet coil units, in which units a plurality of sector-shaped coils are provided, on a substrate at an arbitrary distance from each other, and attaching driving sheet coils thus fabricated to the substrate so as to be opposite a rotor magnet at a close distance. Accordingly, the number of sheet coil units printed on and cut out from a sheet base can be increased so that the efficiency of production can be improved.
