Abstract
A multiple phase, multiple pole stator is wound using two coil winding passes per phase. The stator core is indexed in alternate directions between the winding of individual coils of one phase to the next. As a result, the coils of a particular phase are wound using a first stator index direction for the first winding pass and a second stator index direction for the second winding pass. A winding apparatus for such winding has an arbor assembly which includes a tubular shaft having an expandable mandrel at the forward end thereof which is received in the bore of a stator. The mandrel includes a fixed, radially-extending key and at least one pivotal, radially-extending key. The keys are received in slots or keyways provided in the stator bore to lock the stator to the shaft and to rotatably drive the stator during the winding process. An improved combined winding form and lead guide mechanism assembly is also illustrated wherein a lead guide sliding assembly is located in a cavity in the winding form.
