Automatic winding machine: How to choose a winding machine for toroidal transformers?

Automatic winding machine: how to choose a winding machine for toroidal transformers? Today Vacuz machinery and equipment to give you an introduction, take a look!

Choosing the right winding machine is the key to producing coils. Toroidal transformers how to choose the right winding machine? Here we will ring on the working principle of transformer winding machine, the specific operating process, focusing on the analysis of winding tension (which is dry in the industry), toroidal transformer winding machine operating process is very simple, but want to fix but must find the working principle, winding tension and related knowledge.

Toroidal transformer core using high-quality cold-rolled silicon steel sheet (thickness 0.23mm-0.35mm) seamlessly rolled, the magnetic circuit is completely closed, no leakage, so its magnetic properties Z good, high-precision laser welding, nitrogen and hydrogen protection vacuum annealing, the core of electromagnetic indicators greatly improved.

Toroidal transformers using toroidal winding machine winding fast and convenient production efficiency, can be widely used in electronic equipment 50Hz, 60Hz, 400Hz transformers, transformers, reactors, chokes and other electromagnetic components.

Transformer winding machine working principle

Firstly, the wire is evenly wound on the storage ring, and then the wire wound on the storage ring is wound on the skeleton through the shuttle machine. The skeleton is driven by servo motor to rotate so that the wire is evenly arranged on the skeleton when the wire storage ring is wound to a certain number, then the tape measure is wound on the skeleton through the wire storage ring and then coiled.

Analysis of winding tension

Through the production practice, we found that tightening the wire to wind on the skeleton with proper strength during the whole process of winding is the key to the quality of winding. Therefore, we focus on the factors that affect the winding tension.

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

2. the rotational inertia of the bobbin part (including the wire wound on the bobbin) due to the change in acceleration. The main part of the frictional torque is generated by the tensioning mechanism, which prevents the silk shuttle from releasing the silk movement and pulls the silk tight, thus generating the winding tension. Due to the effect of the winding ring surface and its off-center position in the winding gear, the bobbin speed is small and uniform, even if uniformly wound, thus generating a moment of inertia caused by acceleration, which affects the winding tension. The velocity of the silk shuttle can be seen as consisting of two velocities: a velocity Vo, which is equal to the velocity of the pulley on the winding gear, and a velocity of the amount of silk released by the silk shuttle.
