Abstract

PURPOSE:To simplify the construction of the motor, by tightly fitting a magnetic metal on coated magnetic metal films, which have a prescribed shape and are made on the surface of a nonmagnetic plate and act as stator poles, to manufacture a stator and providing a rotor, a coil, etc. CONSTITUTION:Stator films 4, on which magnetic metal films are made in the form of a stator, are coated around a rotor rotation hole 8 which is provided in a nonmagnetic plate 2 to place a rotor 30. The stator films 4 act as stator poles 4c, 4d. Stator plates 6 of prescribed shape are tightly fitted on the stator films 4 to manufacture the stator. The nonmagnetic plate 2 has a coil positioning hole 10 for positioning a coil 40, shaft support holes 16, 17 for supporting train wheels, a prescribed circuit pattern and holes 23 which are provided in positions corresponding to that of the circuit pattern to insert circuit elements 22. The coated films 4 of the magnetic metal are made by printing, plating, evaporation coating or the like. The nonmagnetic plate 2 is made of oil-containing plastic or the like.
