Abstract
PURPOSE: To reduce a layer-built process of the electromagnetic rail by molding a board unit, in which coils for one line connected with each other in the direction of longer side and insulating material are molded together, insulating paper and covering part in one body.
CONSTITUTION: The coil 6 for one line is set in the metal mold 4 and insulating material containing both thermosetting resin and fibrous glass is filled in such a way that the thickness 8 can be tolerated an extrnal force in carrying. And it is pressed on by the metal mold 5 from the upper side to mold a board unit. The board units are arranged in the mold which comprises the lower side mold 13 and middle mold 12, the fibrous material 9 is inserted between the coil phases and those are covered with fubrous material 10 of desired thickness. After this, thermosetting resin is put into the mild at reduced pressure to mold polyphase coil part, coil gap part and covering part in one body.
