A suitable winding machine is a key part of producing coils

The manufacturer of the winding machine will discuss that selecting a suitable winding machine is the key to producing coils. The working principle and operating process of the transformer winding machine will be explained in detail using a circular transformer, with a focus on the analysis of winding tension (this is a dry product prepared for industry personnel). The operating process of the circular transformer winding machine is very simple, but to be good, it is necessary to understand the working principle, winding tension, and other related knowledge.

The iron core of the ring transformer is seamless rolled from high-quality cold-rolled silicon steel sheets (thickness 0.23mm-0.35mm), with closed magnetic circuit and no magnetic leakage. Therefore, its magnetic performance is excellent, high-precision laser welding, nitrogen hydrogen protection vacuum annealing, and the electromagnetic index of the iron core is greatly improved. The circular transformer utilizes a circular winding machine for fast, convenient winding and high production efficiency. It can be widely used in electromagnetic components such as 50Hz, 60Hz, 400Hz transformers, transformers, reactors, chokes, etc. in electronic equipment.

The working principle of the transformer winding machine: first, evenly wrap the wires on the storage ring, and then use a shuttle to wrap the wires wrapped on the storage ring onto the skeleton. The skeleton is driven by a servo motor to rotate, so that the wires are evenly arranged on the skeleton line. When the winding is completed, the tape is then wrapped on the skeleton through the storage ring, and then wound.

Analysis of winding tension: Through production practice, it has been found that using appropriate force to tighten the wire and wrap it around the framework is the key factor affecting the quality of winding. Therefore, we will focus on the factors that affect the winding tension below.

The inertia moment caused by the acceleration change of the shuttle part (including the wire wrapped inside the shuttle). The main part of the friction torque is generated by the tension mechanism, which prevents the wire shuttle from releasing and tightens the wire, generating winding tension. Due to the influence of the circular surface of the winding wire and its deviation from the center position in the winding gear, even if the wire is wound at a uniform speed, the movement speed of the wire shuttle is small and uniform, which generates inertia torque caused by acceleration and affects the winding tension.
