H01F 41/06 Coil winding
Introduced: September 1968
Full Title
Full titles differ between systems:
Apparatus or processes specially adapted for manufacturing or assembling magnets, inductances or transformers; Apparatus or processes specially adapted for manufacturing materials characterised by their magnetic properties > for manufacturing cores, coils or magnets > for manufacturing coils > Coil winding
Apparatus or processes specially adapted for manufacturing or assembling magnets, inductances or transformers; Apparatus or processes specially adapted for manufacturing materials characterised by their magnetic properties > for manufacturing cores, coils, or magnets (H01F41/14 takes precedence; for dynamo-electric machines H02K15/00) > for manufacturing coils > Coil winding
Additional Content IPC
Former Frame, e.g. composed of electrically insulating material, around which a coil is wound. Examples of former are bobbins, spools or winding supports
IPC and CPC are identically structured here. All 12 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
