This coil forming machine is designed to produce motor coils by opening the loop and forming it into diamond-shaped coil. The parameters of coil forming machine can be programmed by microcomputer during the coil forming process. After manually loading the coil and press the start button, the coil processing machine can automatically control and realize the precise forming of coil evolutes. After a coil is formed, the clamp will be released automatically to enable the manual removal of finished coil, and then the equipment will be reset automatically. The diamond-shaped coils produced by this coil making machine do not have any mechanical damage, and the insulation between the turns of the coil is intact, which ensures the reliable electrical performance of the coil.
