Poly-phase electromagnetic device having an improved conductor winding arrangement

A poly-phase electromagnetic device having n winding phases (where n is greater than 2), said device including:

• n separate electrical conductor phase windings, each completed phase winding being in the form of a continuous electrical conductor strand;
• a magnetically conducive base having a plurality of slots adapted to receive active portions of the phase windings therein;
• each phase winding comprising a series of interconnected lap form sub-windings, with each sub-winding defining two active arms that extend through two spaced apart non-adjacent slots in the base, the active arms being joined by one or more suitably formed end turn and/or two connecting arms for connection with adjacent sub-windings or terminals;
• said active arms and end turn or end turns each formed to include one or more co-extending electrical conductor strands;
• and
• wherein said phase windings are configured such that on assembly of the phase windings to the magnetically conducive base there is a maximum of n−1 sub-winding end turns overlapping, while the lengths of the end turns are simultaneously minimized.
