Choosing the right winding machine is the key to producing a coil. How does a toroidal transformer choose the right winding machine? Here, we will use a toroidal transformer to specifically talk about the working principle and operation process of the transformer winding machine. The emphasis is on the analysis of the winding tension (this is the dry goods prepared for the people in the line), the operation of the toroidal transformer winding machine It is very simple, but if you want to make it, you must understand the working principle, winding tension and other related knowledge.

The core of the toroidal transformer is seamlessly rolled from high-quality cold-rolled silicon steel sheet (thickness 0.23mm-0.35mm). The magnetic circuit is completely closed and there is no magnetic leakage, so its magnetic performance is optimal, high-precision laser welding Nitrogen-hydrogen protection vacuum annealing, the core electromagnetic index is greatly improved.

The toroidal transformer uses a ring winding machine to quickly and conveniently produce high efficiency. It can be widely used in 50Hz, 60Hz, 400Hz transformers, transformers, reactors, chokes and other electromagnetic components in electronic equipment.

The working principle of transformer winding machine

Firstly, the wire is evenly wound around the wire loop, and then the wire wound around the wire ring is wound around the skeleton through the shuttle, and the skeleton is rotated by the servo motor so that the wires are evenly arranged on the skeleton and wound up to a certain amount. Then, the tape is wound around the skeleton through the wire loop and then wound.

Analysis of winding tension

Through production practice, it is found that in the whole process of winding, the wire is tightly wound around the skeleton with appropriate force, which is the key to affect the winding quality. Therefore, we will focus on the factors affecting the winding tension.

1. The grinding torque of the rotating part of the thread bobbin

2. The moment of inertia caused by the change in acceleration of the wire shuttle part (including the wire wrapped around the wire shuttle). The main part of the frictional torque is generated by the tension mechanism, which prevents the wire take-up movement and tightens the wire to generate the winding tension. Due to the influence of the winding annular surface and its deviation from the center position in the winding gear, even if the winding is uniform, the speed of the wire shuttle is small, which generates a moment of inertia caused by the acceleration, which affects the winding. tension.
