ABSTRACT:
A star (wye) connected air gap polyphase armature having limited voltage differences between physically adjacent coil windings at the phase boundary for the different phase circuits. The unconnected lead of the coil or coils at the first edge of the phase belt region forms the neutral terminal for connection of the phase winding in a star or wye circuit comprised of other similarly formed phase windings, and the unconnected lead of the last coil or coils remaining at the middle of the phase belt region forms the line terminal for the multiple coil phase winding to thereby minimize voltage differences between turns of physically-adjacent phase windings at the phase boundaries.
