Abstract
Abstract A coil winding configuration for a three phase winding connected in a Delta configuration for the stator of an alternator for providing a high output at low engine rpm. Each phase of the winding comprises 14 coils which are located in the slots of a 42 slot stator with 8 turns in each slot. Each of the windings is formed of 14 A.W.G. electrically conductive wire.
