METHOD FOR ISOLATION OF MAGNET CORE SLOTS IN MOTOR STATORS Russian patent published in 2014 - IPC H02K15/85 

FIELD: electricity.

SUBSTANCE: in method for isolation of magnet core slots in micromotor stators all surface of the magnet core, excluding slots, is covered by a sealed dielectric shell made of elastic aggressive-resistant material, the magnet core is placed to a container filled with electrophoretic compound, two electrodes are led to butt ends of the magnet core and positive potential is supplied to the magnet core from a direct-current source and negative potential is supplied to the electrodes and electrophoretic precipitation of film-forming material is made; thereafter the magnet core is removed from electrophoretic compound, freed from the sealed dielectric shell and the film precipitated to the slot surface is subjected to thermal treatment during 4-5 min at temperature of 380-390°C.

EFFECT: obtaining higher adhesive and mechanical properties and reducing labour intensity.
