ABSTRACT:
The purpose of this invention is to supply people with a flat core-less direct-current motor of high output torque, high speed and high power efficiency.
It is also a 3 phase flat core-less direct-current motor comprising a fan-shaped flat armature coils of alignment winding in which an included angle constituted by each of coil portions effective for producing a torque exceeds 180 degrees in electrical angle and a disk-shaped rotary armature constituted by the said armature coils arranged at equal pitches within a plane with their outside surfaces made radial and with each adjacent two of them kept in contact with each other and plastic in which the said armature coils are buried or a stationary armature with a magnetic body of a little iron loss functioning as a magnetic path on its one surface.
