Herstellungsverfahren für eine Spule auf einem toroidalen Magnetkreis

摘要

The process involves linearly winding the coil (4) around the toroidal magnetic circuit (1). The coil is then varnished with a thermo adhering varnish. The varnish is a polyurethane modified with polyester and a layer of polyamine. The toroid is then opened out, and the formed coil removed. The coil is then heated, making it flexible. Following this the coil is replaced on the magnetic circuit, and the assembly is allowed to cool.
