Abstract:
An assembly type stator structure having flat wire wound coils, comprising:a plurality of stator tooth portions each having a curved tooth face, a root end being extended rearwards from said curved tooth faces, a root tail end being extended rearwards from a distal end of said root end, a maximal width of said root end being larger than said root tail end; a stator ring having an inner edge or an outer edge either divided into a plurality of embedding grooves having the same number as the stator tooth portions, said embedding grooves being spaced at an equal circumferential angle and recessed toward the direction of the other ring edge, said root tail end corresponding to and being slipped into said recessed embedding grooves of said stator rings; a T-shaped wire groove seat made of insulating material, a flat wire wound coil of an electromotor or a generator being slipped onto a longitudinal vertical pole end of said T-shaped wire groove seat, a hollow position being formed in said vertical pole end, said hollow position being slipped onto or separated from said stator root end, said hollow position being a hollow end of said wire groove seat; said flat wire wound coil formed of a flat wire, said flat wire wound coil having two opposite faces, two opposite sides, a start winding, and a finish winding, said faces being horizontally laminated at an inside of said wire groove seat, said sides being slipped onto said longitudinal vertical pole end of said T-shaped wire groove seat so that said start winding and said finish winding can be exposed, said flat wire being bent and laminated in several turns by a coil forming machine with said sides as a bottom of said flat wire wound coil and said faces as a stacked type.
