What is the difference between multi-wire stator inner winding and single-wire stator inner winding of brushless motor stator winding machine?

Brushless motor stator winding process, is an important part of motor production, the common stator has a slot outward winding process, there is a slot inward winding process, there are many factors affecting the winding, such as stator outer diameter, stator inner diameter, stator height, several lines and winding, wire diameter size, number of turns, number of slots, slot distance, etc.

For the common automatic internal winding machine equipment, many friends do not understand the difference between multi-wire internal winding and single-wire internal winding, only know that a multi-wire winding, a single-wire winding way, so how the specific situation? Let’s take a look!

Generally speaking, the thicker the wire diameter, the more difficult winding, mainly because it is easy to hurt the line, but also easy to scrape off the line, the winding machine generally has more stringent requirements for the wire diameter, single-wire winding, generally not more than 1.3mm, more than that, it is difficult, or the need to customize the machine; multi-wire winding, a single line do not exceed 0.7mm, more than difficult, if the line is less than 0.5mm, the use of 3 If the line is less than 0.5mm, the use of 3, 4 and winding are no problem.

2. motor operation, the current through the coil, there will be a skin effect, the overcurrent capability will have a certain weakening, so multi-wire winding overcurrent capability than a single line better.

3. Efficiency, in the case of conditions permitting, the use of multi-wire parallel winding is beneficial, can improve the efficiency of winding to a certain extent.

The above is the difference between multi-wire winding and single-wire winding in stator winding machine. In general, single-strand winding and multi-strand winding have their own advantages, mainly depending on the needs of their products to determine the winding method.
