Cycloidal Coil Winder

This type of winder can be used to automatically wind any shape coil from round to rectangular. The coils can be spaced from very close together to wide apart.

This device is particularly well suited to winding coils on rectangular mandrels where the height of the mandrel is 2 or more times the width, and for those applications where the space between mandrels is equal to the mandrel width as found in the linear motor "E" core.

The coil winder as shown, is comprised of a drive motor, not shown, two chain sprockets, one chain, and a special coupling link. This link contains the actual coil winder while the chain and sprockets provide the transport system. The winder contains one or two free-floating coils of wire, a needle, and a wire guide. By permitting the coils of wire, the wire guide, and needle to free float, it is possible to wind either bifilar or a single winding on the closely spaced legs of the stepper motor "E" core, or any closely spaced open-ended mandrel. As the needle follows the path of the chain, the coils of wire unwind in a cycloid manner while the "E" core or mandrel is oscillated in a plane parallel to the needle, thus permitting the coils to be wound.
