駆動用成形コイル体の製造方法。2. A coil is formed by making a spiral cut in a conductive tube by electric discharge machining, and the coil is formed by:
Held in an annular molding chamber having an inner peripheral wall smaller in diameter than the inner diameter of the coil and an outer peripheral wall larger in diameter than the outer diameter of the coil,
While maintaining a vacuum state in the molding chamber, an insulating thermosetting resin material in a flowing state is injected into the molding chamber so that no gap is formed between adjacent coil wires, and the injected thermosetting resin material is cured. After forming the molded body, the molded body is taken out of the molding chamber, and finally, the conductive coil cut out and formed by electric discharge machining has an inner diameter smaller than the inner diameter of the coil and is formed outside the coil. Manufactures a molded coil body for driving that is integrally coated with an insulating material made of a tubular thermosetting resin material with an outer diameter larger than the diameter so that there is no gap between adjacent coil wires over the entire surface Characterized in that
A method for manufacturing a molded coil body for driving.

ル体の製造方法。3. A tube is formed by forming a through-hole concentric with the conductive column in the center of the conductive column by electric discharge machining, and a spiral cut is made in the tube by electric discharge machining. Forming a coil, holding the coil in an annular molding chamber having an inner peripheral wall having a smaller diameter than the inner diameter of the coil and an outer peripheral wall having a larger diameter than the outer diameter of the coil. Insulating thermosetting resin material in a flowing state is injected into the same molding chamber while maintaining the state so that no gap is formed between adjacent coil wires, and the injected thermosetting resin material is cured to form a molded body. After that, the molded body was taken out of the molding chamber, and finally, the conductive coil cut and formed by electric discharge machining had an inner diameter smaller than the inner diameter of the coil and a larger diameter than the outer diameter of the coil. Insulation made of cylindrical thermosetting resin material with outer diameter of A method for manufacturing a formed coil for driving, characterized by manufacturing a formed coil for driving integrally covered with no gap between adjacent coil wires over the entire surface.
