Series-wave windings for dynamo-electric machines

Claim 2

Series-wave winding for multipolar dynamo-electric machines having at least three pairs of inductor field poles on one face of the magnetic airgap thereof, wherein the electrical circuit of the winding progresses by waves each covering a quadruple polar pitch.

Claim 3

Series-wave winding according to claim 1 wherein the winding is of general discoidal shape and wherein the winding is made of a thin insulated wire in a plurality of overlays with the turns of said wire each comprising a first substantially radial outer portion which substantially spans over one polar pitch and a transverse and substantially linear portion reaching a further radial outer portion, also of one polar pitch span, which is spaced apart angularly from the first by approximately one quadruple polar pitch of the winding.

Claim 4

Series-wave winding according to claim 2, wherein part of such turns present inner loops shifted with respect to the winding band defined by the other turns in said winding.

Claim 5

Series-wave winding according to claim 2 including a thermosettable resin molded over said overlays of insulated thin wire.

Claim 6

Series-wave winding according to claim 4, including an insulating rigid carrier disc supporting said overlays of insulated thin wire and moulding resin.

Claim 7

Series-wave winding according to claim 5, wherein said carrier disc includes a plurality of pins defining the spans of the said outer radial portions of the turns.
