ABSTRACT:
Single and multi-phase, multi-pole arrays of adjacent equivalent current loops are formed in a self-supporting structure as wound. The multi-pole windings are formed by zig-zag winding elements having peaks and troughs. The peaks and troughs of each winding element form alternate halves of adjacent effective or equivalent current loops. When the peaks of one winding element are aligned with the troughs of another, the two elements provide a single phase ring of adjacent coupled current loops equivalent to the conventional separately wound coils. However, the current loops are already in a correctly positioned and oriented array as wound. The filaments of one winding element cross over the filaments of another intermediate the peaks and troughs and current passes in one direction through the first element returning in the opposite direction through the second. Multi-phase windings in a variety of configurations are described. The annular windings are wound on an arbor by a new winding apparatus and simplified method according to the disclosure. Windings are removed from the arbor and are particularly applicable for use in sensing and torque producing devices.
