Claims
- 1. A hysteretic tensioning apparatus for substantially stabilizing tension in a conductive wire supplied to a winding machine, said apparatus comprising:a support member; a brake member mounted to said support member, said brake member rotatable relative to said support member, said brake member is a current controlled brake member and is configured to apply substantially constant tension to the conductive wire during winding; and a plurality of idler arms pivotally mounted to said support member, said plurality of idler arms configured to engage the conductive wire between a wire source and the winding machine.
- 2. An apparatus in accordance with claim 1 wherein said brake member is a rotatable disk.
- 3. An apparatus in accordance with claim 1 wherein at least one of said idler arms is a spring loaded idler arm.
- 4. An apparatus in accordance with claim 1 comprising four idler arms.
- 5. An apparatus in accordance with claim 1 wherein at least one of said idler arms comprises a first end and a second end, said first end pivotally coupled to said support member, said second end configured to engage the conductive wire.
- 6. A method for stabilizing tension in a conductive wire supplied from a wire source to a winding machine, the method employing a hysteretic tensioning apparatus including a support member, at least two idler arms pivotally coupled to the support member and adapted for engaging the conductive wire, and a brake member that is current controlled, said method comprising the steps of:positioning the hysteretic tensioning apparatus such that the at least two idler arms are between the wire source and the winding machine; and coupling the conductive wire to the hysteretic tensioning apparatus.
- 7. A method in accordance with claim 6 further comprising the step of coupling the conductive wire to the winding machine.
- 8. A method in accordance with claim 6 wherein coupling the conductive wire to the hysteretic tensioning apparatus comprises the step of extending the conductive wire between the current controlled brake member and the two idler arms.
- 9. A method in accordance with claim 8 further comprising the step of engaging the conductive wire to the brake member.
- 10. A method in accordance with claim 8 further comprising the step of engaging the conductive wire to at least one of said idler arms.
- 11. A winding system for winding a wire, said system comprising:a wire source comprising at least one conductive wire; a tensioning apparatus comprising a support member, at least two spring loaded idler arms, and a brake member mounted to said support member, said brake member is a current controlled brake member; and a winding machine, said conductive wire coupled to said tensioning apparatus and extending between said wire source and said winding machine, said at least two idler arms engaging said conductive wire between said wire source and the winding machine.
- 12. A winding system in accordance with claim 11 wherein said brake member rotatable relative to said support member, said at least two idler arms pivotally coupled to said support member.
- 13. An apparatus in accordance with claim 12 wherein said brake member is a rotatable disk.
- 14. An apparatus in accordance with claim 12 comprising four idler arms.
- 15. An apparatus in accordance with claim 11 wherein each idler arm is pivotally coupled to said support member.
- 16. An apparatus in accordance with claim 11 wherein each idler arm comprises a first end and a second end, said first end coupled to said support member, said second end configured to engage the conductive wire.
