Transformer core winder producing coil groups - winds turns in cyclic symmetric pattern to reduce radial dimension

摘要

A winding machine is for transformer windings formed by a number of groups of coils. The process provides a winding with a reduced radial dimension where the length is equal to the circumference of the coil. This increases the space factor for the core window. The use of active material is also reduced. The turns are wound in a winding cycle to produce a group of coils (1) by operating in a given order. A given number of turns is formed into a coil (9) of a group of coils from all the wires forming this coil. The wires are then split into two subgroups and the turns interlinked in a cyclic manner.
