<p>PROBLEM TO BE SOLVED: To provide a method and device for eliminating a partial insulation coating in circumference direction from the outer-periphery surface of a magnet wire for forming a tap at the magnet wire. SOLUTION: An insulation coating elimination device 41 with an electric motor 54, a whetstone 60 connected to the tip of the electric motor 54, and pulleys 44A and 44B is used. The whetstone 60 is rotated by the electric motor 54. To eliminate a coating, a specific tension force is applied to a magnet wire 34, and a magnet wire is placed on the pulleys 44A and 44B. Then, the whetstone 60 is rotated and is brought into contact with the wire 34, thus exposing a conductor and hence eliminating a partial insulation coating in circumferential direction from the outer-periphery surface at a tap formation region and reducing the coating elimination area drastically as compared with before. Therefore, even if a coil is manufactured and wires are connected to the exposed conductor by soldering, the possibility of short-circuiting can be reduced drastically, thus improving reliability and yield.</p> |
