PURPOSE:To improve the combining strength and to enhance reliability, by combining insulating tubes and an end part insulator by the adhesive power of resin and the mechanical combining power of fibrinous material. CONSTITUTION:A coil main body 9 is formed by winding a conductor 10 via interlayer insulators 11 on the inner insulating tube 1 which is formed by impregnating thermosetting resin 2 into the fibrinous material. The outer insulating tube 12 which is formed by the same material as that of the inner insulating tube is provided on the coil main body 9. By preliminarily drying said device, the resin 2 in the insulating tubes 1 and 12 is perfectly cured. Then the thermosetting resin 14 is injected, heated, and cured, and the insulating tubes 1 and 12 and the end part insulator 15 are strongly combined. |
