Abstract

PURPOSE:To increase the mass-productivity of the subject motor system as well as to miniaturize the whole system by a method wherein a plurality of armature coils for a magnetic rotor and axial void type motor are provided on the upper and the lower surface of a yoke respectively. CONSTITUTION:A plurality, three for example, for rotating shafts 10, 20 and 30 for the motor are rotatably supported by the bearings 12, 13 and 14 provided at the first substrate 1, and the multipole-magnetized field magnets 15, 25 and 35 which will become rotors are fixed. And, in order to generate rotational torque on the field magnets 15, 25 and 35, armature coils 16, 26 and 36 where current is conducted by the prescribed controlling circuit are provided on the second substrate 3, which is a magnetic substance yoke, in such a manner that the armature coils 16 and 26 are placed on the upper surface of the second substrate 3 and the armature 36 on the lower surface of the second substrate 3, thereby allowing them to face against the field magnets 15, 24 and 35 through the intermediary of the axial void.
