APPARATUS AND METHOD FOR WINDING AND INSERTING COILS IN CORES OF DYNAMOELECTRIC MACHINES

摘要

An apparatus and a method for winding wire coils (C) and forming wire conductor leads (CL) connected to the wire coils. The coils are wound on a winding form (10', 10") and transferred on an insertion tool (46) for subsequent insertion into the slots of the core of a dynamo electric machine. The coils are wound with a stratification disposition which needs to be maintained during the transferring operation on the insertion tool. An expulsion member (20) for transferring the coils from the winding form (10', 10") to the insertion tool (46) is able to push the coils to selected positions (62) along the guide bars (46') of the insertion tool, so that the stratification disposition of the coils is not lost. The wire conductor leads (CL) extending from the transferred coils are formed without impairing the stratification disposition of the already transferred coils. The expulsion member (20) is kept adjacent to the already transferred coil during formation of the wire conductor leads, to avoid that the wire is pulled away from the already transferred coil.
