COIL FRAMEWORK FOR INSTALLATION ON MAGNETIC CORE, MAGNETIC CORE FOR REACTIVE CONVERTERS AND METHOD OF MANUFACTURE Russian patent published in 2015 - IPC H02K3/52 H01F3/00 H01H50/04 

FIELD: electricity.

SUBSTANCE: invention relates to a coil framework for installation on a magnetic core for rotating electrical machine or to a converter and respective magnetic core. The offered coil framework has a bush (102) for winding, which contains a depression (124) for engaging a tooth (116) of the magnetic core (118), at least, one holding rib (114) which is integrated with it and interacts with the holding structure (120) of the magnetic core (118) fixing the coil framework on the tooth. The magnetic core contains a set of thin plates (136) made of sheet metal which are layered over each other in a plane-parallel style and interact so that every two thin plates which are placed over each other, are rotated to a shift angle with reference to each other for the purpose of forming of the holding structure (120).

EFFECT: fixing of frameworks of coils on teeth of the magnetic core and ensuring reliable sitting with long-term stability in operation, and the coil framework can slide along a tooth with a possibility of engaging/disengaging in the radial direction.
