Armature winding for a static converter-fed electrical induction machine

摘要

An armature winding is provided for an induction machine with an odd phase number m>/=5 which has m connection points for its winding sections to a converter. Connections to the converter are made that first and second (m-1)/2 phase windings have current flow in opposite directions and the remaining phase winding advances outwards in electrical angle steps of ( pi /m). A higher pulse number and thus good concentricity characteristics with high machine efficiency can be attained with star or polygonal circuits of the phase windings, and an improved optimal adjustment of the load-bearing capacity of the most varying electronic components can be attained by the polygonal circuitry having multiple rings of the phase windings.
