Use of fractional-conductor windings and semi-magnetic slot wedges in synchronous machines

Use of fractional-conductor windings and semi-magnetic slot wedges in synchronous machines

This paper discusses two methods of altering the harmonic content of the spatial air-gap flux density waveform in synchronous machines (generators and motors). First, fractional-conductor windings are analysed for adoption as a replacement for a conventional distributed winding arrangement, their ad...
