US Patent 7191974 Winding machine including actuated collet

An apparatus for winding the stator for a dynamoelectric machine is provided. The apparatus includes a stator nest located on a mounting member, the stator nest including a front side for receiving a stator and a back side located opposite from the front side. The stator nest defines a horizontal longitudinal axis and includes a collet located at the front side for engaging and gripping the outer surface of a stator positioned within the collet. A collet actuator is located on a side of the mounting member opposite from the front side, and the collet actuator actuates the collet to engage with and disengage from the stator. A winding tool extends through the stator nest from the back side toward the front side. A reciprocating driver is connected to the winding tool for driving the winding tool in reciprocating movement relative to the stator nest. An oscillating driver connected to the winding tool drives the winding tool in oscillating movement. A wire feeder for feeding wire through the winding tool is supported adjacent the oscillating driver and is supported for reciprocating movement with the winding tool.
