This coil winding machine is designed to realize the function of auto winding, auto arraying, slot acrossing, auto getting through wax tube and output setting, etc. This winding machine is suitable for winding the coil for big power motor. The tooling could be auto extend and retract. Therefore, it is no need to discharge the tooling when taking out the finished coil. Thus it can reduce the labor and improve the effciency. It could produce different dimension coils which is for same series size stator by adjusting the tooling, and tension is adjustable too.
