The development of the motor winding machine has experienced many technical reforms and innovations. From the early hand-cranked motor winding machine to the current fully automatic CNC motor winding machine, the efficiency and performance have been greatly improved, and the degree of automation of the equipment has also increased. The higher the coming, many modern high-tech have gradually appeared in the motor winding machine control system. The technological development of the motor winding machine controller is roughly divided into three stages: simple control system, CNC control system, and servo high-precision control.
(1) Simple motor winding machine control system
The system was applied to the early simple motor winding machines, with very simple functions. It could only realize simple functions such as electronic counting, output accumulation, and spindle forward and reverse control. The core control unit generally uses a single-chip microcomputer. At present, most middle and low-grade motor winding machine control systems on the market adopt this control method, using a single-chip control system. Compared with the early manual motor winding machines, it has a high degree of automation, small size, and high control accuracy, which reduces the labor of workers.
(2) CNC motor winding machine control system
The CNC control system was born in the United States and prevailed in Europe, America and Japan. Taiwan’s application of CNC control system was earlier, and domestic manufacturers started late. Therefore, the stability and performance of early domestic CNC controllers are not as good as those of Taiwan’s original products. With the development, CNC controller is currently the most used controller for automatic motor winding machines. Its superior expansion performance makes CNC motor winding machines have more classifications, such as single axis and multi axis. The application of PLC in the CNC automatic motor winding machine uses the internal soft contacts of the program to replace the previous mechanical contacts, the internal counter of the program replaces the previous dialing counter, and the use of the touch screen can shorten the design cycle, and the installation and commissioning are very convenient. Convenient, not only satisfies sequential logic control and timing/counting control, but also ensures the accuracy of position control.
(3) Servo high precision motor winding machine control system
The emergence of high-precision control system is to meet the requirements of modern high-precision and high-quality enameled wire coils. Because the automatic motor winding machine adopts the design of double servo plus PLC, its control accuracy is much higher than that of ordinary motor winding machine control systems. The PLC control unit makes the function of the motor winding machine more customizable, and is often used for coil processing with higher precision.
