Abstract
A coil form bobbin (20) for winding coil winding wire is a flat disk (22) formed with a plurality of peripheral radial slots (24,25,26) comprising at least one set of n slots spaced around the periphery of the flat disk dividing the bobbin into a respective set of n segments. The slots extend from the outside perimeter part way the flat disk. A method for winding flat coil windings on the coil form bobbin is described. The coil winding is in flat configuration for rotor and stator applications. Each winding phase (44,45,46) of multiple turns of coil winding wire is wound in the configuration of a flat substantially regular polygon. The multiple turns of coil winding wire turn in the same direction for conducting electrical current in the same rotational direction around the phase. The multiple turns of coil winding wire lie substantially next to each other side-by-side in the flat array along the sides of the polygon and are formed with well defined similar, radially aligned angles stacked one outside the other at each of the apexes or nodes of the polygon.
