PURPOSE:To improve the cooling effect by forming monolithically a cooling pipe with the coil end and a resin by winding the pipe around so as to be connected on the undersurface of the coil end. CONSTITUTION:A coil 2 is mounted in the slot of the iron core 1 and a copper cooling pipe 3 is embedded on the bottom of the slot. The cooling pipe 3 gets in contact with the coil 2 at a point. It is horizontally connected like U at the one end of the coil 2 while vertically connected like U at the other end 2b thereof. The coil 2 and the cooling pipe 3 are solidly molded with a heat-proof resin. |
