Many friends design brushless motor stator products, in order to achieve a certain use of demand, the need to use multi-strand winding, speaking of multi-strand winding, it can not be separated from the winding equipment, the following Norwon simple to introduce it to you!

In fact, multi-strand winding is also a lot of restrictions, some friends design a good way to wind, often winding machine manufacturers are difficult to do, why? Because the winding equipment is not so well understood, such as the wire diameter is too large, too many strands or too small slot distance and other reasons, so be sure to fully understand the winding equipment, to determine their own design way in line with most of the custom needs of winding machine manufacturers.

multi-strand winding

1. Enameled wire too many strands, too many strands will be involved in over the line and other issues, for the flying fork winding machine, some can reach 30 strands, but the wire diameter requirements are relatively thin; internal winding machine will be less.

2. The wire diameter is too large, flying fork 30 strands together and winding, the wire diameter is generally below 0.3mm, with the increase in single-strand wire diameter, it will affect the winding equipment over the line, so be sure to control the enameled wire diameter.

3. Stator slot distance is too small, enameled wire to wind in from the slot, you need to be able to pass the line and the needle bar, if the line and the needle bar can not pass, no matter how many strands of wire, it can not be wound.

4. Stator outer diameter, inner diameter, height more than custom needs, most manufacturers accept custom needs, if more than a certain limit, may not do.

Stator multi-strand winding is difficult? In fact, it is not difficult, mainly depends on whether the stator products meet the winding needs, too many strands, wire diameter is too large, the slot distance is too small, etc. will affect the winding equipment, so be sure to calculate all aspects of the parameters to determine the majority of winding machine common.
