Modern transformer is composed of core, coil and insulation materials together, the coil is usually divided into high-voltage coil and low-voltage coil, in which the high-voltage coil using insulated wire for winding. Coil winding is the center of transformer production, on the transformer work function has a greater impact, not only directly affect the transformer size, but also affect the transformer insulation function and mechanical function. Existing winding machine is generally semi-active winding machine, the operating process is: the motor drives the workpiece together with the rotation of winding, through the counting device will surround the number of laps now on the appearance, workers manually line up, according to the appearance of the number of laps around the control motor start and stop. But it has the following shortcomings: because of the manual line method, the workpiece processing quality is too dependent on the level of skill of workers, and when the motor speed is too fast, the human operation can not keep up with the motor speed, so restrained the processing power. Although the presentation of fully active winding machine to deal with the production of semi-active winding machine some of the disadvantages, but the existing active line winding machine for a single insulation layer supply, can not complete the line with synchronous surround or coil side insulation paper around, the low degree of initiative and process is not complete. Traditional transformer coil winding are relying on human power to insulate the layer according to the production process around the component, the operator statistics turns, the use of traditional winding methods are affected by human factors, resulting in low winding power. Therefore, the use of fully active transformer winding machine to deal with the problem .

For the above problem, a servo system is used to drive the wire arrangement mechanism, build the hardware platform, and combine the software part of the control system design to complete the transformer winding process. In order to complete the fine winding, the tension in the enameled wire and insulation tape needs to be controlled, this paper discusses the active wire arrangement control technology for fully active transformers, in order to lay the foundation for the tension control of the insulation tape.
