The invention discloses an external embedded coil winder, includes a winding die disk having an outer diameter smaller than an inner diameter of a core slot, A meter-shaped win die support is coaxially arranged on that inner wall of the winding die disk, and a rectangular hole connected with a winding rotating device through a rectangular drive rod is arrange at the center of the meter-shaped winding die support for passing through the winding rotating device connected with the rectangular drive rod; Between that wire win die disk and the iron core slot, an adjustable limiting mechanism is arrange for limiting the conductor in the wire winding process. The invention has simple structure, and is mainly applied to the winding operation of the embedded coil outside the iron core of the electric power equipment. The coil can be directly wound in the iron core outer slot, the wire slot need not be divided and assembled, the manual wire arrangement is not required, the winded coil wire has tension, the coil is compact and is not easy to loosen. On the premise of ensuring the level of winding coil, the working efficiency is greatly improved, and it is convenient to use rotating equipmentto assist winding and reduce the labor intensity of operators.
