Abstract
An apparatus for forming varied length wire coils for insertion stator core slots includes a template positioned that is configured to vary a length of consecutive wire turns while wire is received from a flyer winder. The wire turns may then be inserted into a pair of stator core slots depending upon their respective lengths. A method of using the apparatus to form a winding with varied length turns includes depositing wire turns on a template, varying a length of at least two consecutive wire turns as the wire is deposited on the template, removing the wire turns from the template, and inserting the removed wire turns into a stator core slot.
Claims34
An apparatus for forming wire coils from wire turns with varied lengths, comprising:
- a template positioned to receive wire from a winder, said template being configured to vary a length of at least two consecutive wire turns during receipt of said wire;
- and
- an insertion tool, which includes:
- i) a coil support that collects said wire turns in an order that is dependent upon their respective lengths;
- and
- ii) a coil constraint which maintains said wire turns in a coil in said collected order.
A method of forming wire coils that have varied lengths, comprising the steps of:
- varying a length of at least two consecutive wire turns as said wire turns are formed on said template;
- collecting said wire turns in an order that is dependent upon their respective lengths;
- and
- maintaining said wire turns in a coil in said collected order.
