From the fan winding structure design, not all coils used can be produced using vertical winding machine. Such as layer structure, multi-spiral structure type coils. If such coils are wound using ordinary horizontal winding machines, the axial direction is wound without any pressure, and the gap between the wire segments is large, like a compression spring. The diameter of the coil of automatic fan winding machine becomes larger after being pressed, and the gap between the coil and the paper cylinder will cause axial instability of the coil, and in case of axial electric force, the coil may cause damage. Therefore, horizontal winding machines with axial and radial compression are widely used in the production of large fan coils. As fan performance requirements become higher and higher, the production of small and medium-sized fans has gradually started to use compression type horizontal winding machines.

1、No brush, low interference

Brushless motor removes the brush, the most direct change is that there is no electric spark generated by the brush motor operation, which greatly reduces the interference of electric spark to remote radio equipment.

2、Low noise, smooth running

Brushless motor without brushes, friction is greatly reduced when running, smooth operation, noise will be much lower, this advantage is a huge support for the stability of the model operation.

3、Long life, low maintenance cost

With less brushes, the wear and tear of brushless motor is mainly on the bearings. From the mechanical point of view, brushless motor is almost a kind of maintenance-free motor, and when necessary, it only needs to do some dust removal maintenance.

Now, due to the rapid development of machining technology, the production cost of brushless motor has dropped a lot, and it is now entering all levels of the model field, from electric RC cars to electric RC boats to electric model airplanes, the cooling fan winding machine is everywhere.
