Abstract

PURPOSE: To improve thermal conductivity between a core and a winding in case electrodeposition process is employed by a method wherein the winding is installed on the core being insulated through electrodeposition process, and then the said process is again applied to fill a void left in a slot.
CONSTITUTION: A core 1 is put in an electrodeposition liquid 3 consisting of a water soluble varnish or a varnish dispersion containing inorganic matter like mica powder, and current is carried between the core 1 and an electrodeposition tank 2 to form an electrodeposition layer 6 on the core surface. After applying an irregular winding 4 on a slot of the core 1, electrodeposition is again carried out with a water soluble varnish or a varnish dispersion containing inorganic matter like silica powder as an electrodeposition liquid, and thus an electrodeposition layer 7 is formed in a void left in the slot. By arranging such as described, a thermal conductivity in the slot is improved, a flaw arising between layer insulation can be restored, and further the air pollution due to a volatilization of solvent can be prevented.
