What is the impact of the coil of the cooling fan winding machine?

From the structural design of fan windings, not all the coils used can be produced by vertical winding machine. Such as layer structure, multi-helix structure coil. If this kind of coil is wound without any pressure in the axial direction after it is wound by an ordinary horizontal winding machine, the gap of the line segment is very large, like a pressure spring. The diameter of the coil of the automatic fan winding machine becomes larger after compression, and a gap occurs between the coil and the paper tube, which will cause axial instability of the coil. In case of axial electric force, the coil may be damaged. Therefore, the horizontal winding machine with axial and radial compression has been widely used in the production of large fan coils. With the higher and higher performance requirements of fans, the general production of small and medium-sized fans also gradually began to use compression horizontal winding machine.

1. No brush and low interference.

The brushless motor removes the brush, and the most direct change is that there is no electric spark when the brushed motor is running, which greatly reduces the interference of the electric spark to the remote control radio equipment.

2. Low noise and smooth operation.

Brushless motor without brush, running friction is greatly reduced, running smoothly, noise will be much lower, this advantage is a great support for the stability of the model operation.

3. Long life and low maintenance cost.

Less brushes, brushless motor wear is mainly on the bearing, from a mechanical point of view, brushless motor is almost a maintenance-free motor, when necessary, only need to do some dedusting maintenance.

Now, due to the rapid development of machining technology, the production cost of brushless motor has dropped a lot. at present, it is entering all levels of the model field, from electric remote control vehicle to electric remote control ship to electric model aircraft. heat dissipation fan winding machines are everywhere.
