US Patent:

48847585, Dec 5, 1989

Filed:

Dec 11, 1987

Appl. No.:

7/132091

Inventors:

Clark J. Hamkins - Lexington KY

Assignee:

Kuhlman Corporation - Troy MI

International Classification:

H01F 4106

US Classification:

242 4BE

Abstract:

Apparatus for winding a continuous length of wire about a mandrel to create coils of wire uses a coil winding machine having a circular cage mounted to a frame and a circular winding magazine freely rotatably mounted to the frame within the cage to define an annular cavity between them. Initially a supply of wire is wound on the magazine, such as counterclockwise. The wire on the magazine continues to be connected as a continuous strand to a large, external spool of wire. A winding shuttle is driven along the annular cavity clockwise to remove wire from the magazine and wind it about a mandrel. Wire is removed from the magazine at double the rate at which it is wound about the mandrel. The excess wire initially expands within the cavity. The expansion is halted by the cage.

Kuhlman Corporation - Troy MI

International Classification:

B65H 8102

US Classification:

242 702

Abstract:

A winding apparatus and method for fabricating a multifilar low voltage winding for a toroidal transformer is disclosed. The method and apparatus use a wire storage magazine (18) and a wire winding shuttle (20) which rotate about a semitoroidal winding mandrel (38) to wind a multifilar low voltage winding (48) on the winding mandrel having a greater radial depth of turns at the radially inward leg of the winding than at the radially outward leg of the winding. The multifilar winding can be wound with a group of conductors in a single pass over the winding mandrel, or wound one conductor at a time using multiple passes over the winding mandrel, or wound using multiple passes over the winding mandrel with some intermediate number of conductors being wound during each pass.
