Abstract
Winding assemblies of electrical machines, such as electric motors, are provided which include a connector scheme having at least one conduit that is electrically coupled via a wave soldered connection directly to at least two windings which are not axially adjacent. The conduit can include a common connector and/or a phase connector. The connector scheme can additionally or alternatively include a power connector that is electrically coupled via wave soldering directly to a single winding, and adapted to be electrically coupled to a power source. The winding assemblies of the invention can additionally provide a number of constructions which allow for minimally sized air gaps.
