Is it difficult to wind multiple strands inside and coarse wire in automatic BLDC motor stator coil winding machine?

Stator winding requires special winding equipment, like the slot inward brushless motor stator, it is commonly used inside the winding machine to solve the winding problem, stator size, shape, parameters vary, general products can be common a device, winding is relatively easy, but if it is multi-stranded wire or winding thick wire, there will be difficulty? What are the problems to pay attention to?

1. multi-wire winding, many friends do not want to use thick wire winding, choose multiple wire and winding way, generally according to the wire diameter, you can two or more wires together and wind. 0.5MM wire diameter, generally only two wires and winding; 0.5MM below, you can use multiple wires and winding way. Of course, also related to the parameters of the stator, including slot, stack thickness, etc., winding, the need to reduce the speed, multiple lines swing arc, easy to scrape the line, resulting in damage to the enameled wire, leakage value does not meet the demand.

2. Thick wire inside winding, like power tools, garden tools brushless motor products, wire diameter are relatively thick, many are more than 1.0MM, winding headache is the problem of injury wire. When winding, you need to reduce the speed, you can do some detailing at the line mouth, such as enhanced needle swing process, to prevent the swing arc too large, reduce the chance of rubbing the line, making the line loss reduced.

As you can see, automatic winding machine multi-strand winding and winding thick line is certainly difficult, many manufacturers do not do well in this regard requirements, which we must pay attention to, in the choice of winding machine, be sure to ask more about the manufacturer is good at technology and reputation, can not be greedy for cheap, or buy a machine, the results of the injury line can not be solved, it is not worth the loss.
