Abstract
A ring coil winding assisting device for winding with an enamel wire to form into a ring coil, consisted of two symmetrical annular insulation shields and an iron core insulated in between, one insulation shield having a projecting stator at the top in parallel with the central axis of the iron core for fastening one end of the enamel wire to be wound, the stator having a circularly smooth ridge around the periphery for passing the enamel wire during its winding.
Claims4
A ring coil having an annular iron core extending about a central axis comprising:
- a) first and second annular insulation shields surrounding the annular iron core;
- b) a single stator projecting from one of the first and second annular insulation shields in a direction parallel to the central axis, the single stator having a distal end;
- and
- c) an insulated wire wrapped around the first and second insulation shields in toroidal configuration, the insulated wire having an end attached to the single stator, and an outer surface of the wire toroid being substantially flush with the distal end of the single stator.
