There is a big difference between using Coil winding tensioner device and not using tension device on winding machine. Here we summarize some advantages for reference only: 1: Ensure the consistency of coil electrical performance and production process technical indicators; 2: The required tension can be controlled at will with high precision to improve the appearance of the coil and make the coil flat and full. 3: It can save enameled wire, which may be very small for a single
