Abstract

PURPOSE:To easily form the layer in very short time for the subject commutator by a method wherein an insulator layer is provided on the outer circumference of a boss by applying a powdery material coating method. CONSTITUTION:A cleaning solution such as trichlene or the like is applied on the outer circumference of the boss 1 and its surface is cleaned. Then the surfaces where no powdery insulator is allowed to be adhered to, for instance, such as the surfaces on both ends of the boss and the inner surface of the boss hole, are masked by sticking a silicon adhesive tape on the surfaces and then the boss is preheated at the proper temperature, for example at approximately 220 deg.C, so that the insulator will be fused speedily and deposited on the boss. A filter 7 is installed at the lower section of the container 6 of a powdery material coating vessel, on which powdery material 9 of powdery material insulator is placed, the powdery material 9 is wafted by sending air from an air inlet 8 located at the lower section of the container, the preheated boss 1 is hung down using a wire 10 and an insulator layer is formed on the outer circumferential surface of the boss. Hence the layer can be formed easily in a very short time.
