ABSTRACT:
A method for winding a field assembly for a universal motor and apparatus produced thereby is disclosed. The method involves winding both a field winding and a brake winding over different field poles within a field core simultaneously. After the first field winding and the first brake winding are wound, the field core is indexed to allow a second brake winding to be wound over the first field winding, and a second field winding to be wound over the first brake winding. By using the disclosed method, a field assembly is produced in which both field windings and the brake windings are wound using one continuous wire for each. Moreover, the presented method can be performed on a single winding machine.
