Abstract
The reciprocating and oscillating winding spindle of a stator winding machine is rotatable through 180° to enable a stator winding and lead terminating method and apparatus for automatically winding a 2-pole stator having two pole pieces each with a coil wire wound from the same, single strand of wire. A cross-over wire segment between the two stator coils extends through the bore of the stator and is trapped against an inside wall of the stator by a cross-over wire retaining member. A stator coil lead terminating apparatus is capable of complex manipulations of stator coil lead wires at a winding station. Stator coil lead wires can be looped about wire guide posts on a stator core in the course of forming coil lead terminations, and the posts can be protected against bending or breaking by looping pins that partly receive the posts.
