Automatic winder for an inside brushless stator

Abstract

An apparatus for manufacturing an internal wound stator includes a winding arbor configured to receive a conductive wire. The apparatus also has a stator loader with a stator having a generally cylindrical shape with an interior opening and having a plurality of axial slots formed therein. The interior dimension of the stator is larger than the exterior dimension of the winding arbor such that the winding arbor and stator may traverse with respect to one another. The apparatus also has a first movable member configured for moving at least one of the winding arbor and the stator. The apparatus also has a second rotating member configured to rotate at least one of the stator and the winding arbor. The conductive wire is introduced through an interior of the winding arbor. The first movable member is configured to move at least one of the winding arbor and the stator relative to one another to wind the conductive wire in a first longitudinal manner and into a first of the plurality of axial slots. The second rotating member is configured to rotate at least one of the first winding arbor or the stator relative to one another to align the wire relative to a second axial slot of the plurality of axial slots. The first movable member is configured to move at least one of the winding arbor and the stator relative to one another to wind the conductive wire in a second opposite longitudinal manner and into the second axial slot.

Description

RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application No. 60 / 831,508, filed on Jul. 18, 2006, which is herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to the manufacture of electric machines, such as a motor or a generator, and in particular to a machine that automates a wire winding of a stator. Manufacturing machines typically involve time and labor in order to wind or wrap wires around and / or within the axial slots of a stator. Such machines are costly and often involve complicated assemblies, which require a great deal of post manufacturing finishing operations in order to complete the stator. Accordingly, there is a need in the art for a manufacturing apparatus that is cost effective and that can rapidly manufacture a number of stators in a quick and automated manner.SUMMARY OF THE INVENTION[0003]According to a first embodiment, there is provided an apparatus for manufa...
