Producing rotor for electrical machine with permanent magnetic stimulation involves heating baking lacquer coated magnets in plate packet openings until coating softened so magnets are baked together, to base body at coated contact surfaces

摘要

The manufacturing method involves first coating the permanent magnets (17) with a baking lacquer coating (19), placing them in openings (16) in a plate packet (15) and finally heating the baking lacquer coating until it is sufficiently softened that the coated magnets are baked together and to the base body at their coated contact surfaces . An independent claim is also included for an electrical machine with a stator and a permanent magnetic rotor.
