ABSTRACT:
Generators which comprise, within a casing, an armature and a permanent-magnet cylinder surrounding said armature, either of these two components serving as a stator with the other as a rotor to rotate in union with a rotary shaft, and which may supply electromotive force from a coil in said armature.
Said armature comprises a cross-shaped 4-pole core and a coil; said coil is wound on a bobbin, placed on one of the two straight core components, in parallel with the other core component.
The directions of the coil windings in one half of the coil and in the other half are opposite to each other.
The above structure is effective for increasing the efficiency of power generation, reducing the size and weight, and cutting down the manufacture cost.
