What are the differences between single-wire winding and multi-wire parallel winding in brushless mo

For the winding of the stator of a brushless motor, professional winding machines are generally used. There are mainly two types of equipment: the flywheel winding machine and the needle-type winding machine. The flywheel winding machine is used for stators with slots facing outward, while the needle-type winding machine is used for stators with slots facing inward. So, what are the differences between single-line winding and multi-line parallel winding in the stator winding machine of a brushless motor? What are the actual differences between the two? 
 

1.The flying hook winding machine is a relatively common winding machine equipment. It can be used with most external stators. Most products are single-wire wound, while there are also multi-wire wound ones. Single-wire winding is relatively faster, while multi-wire parallel winding is slower. In fact, there is no significant difference. The winding process is basically the same. However, due to different product requirements, for example, some products need to use large wire diameters. Single-wire winding is prone to damaging the wire, so it is changed to multi-wire parallel winding to solve the winding problem. 
2. Most of the needle-type winding machines are for single-line winding, with the wire diameter reaching up to 1.3mm. The winding process is relatively easy. Common multi-line winding types include double-line and triple-line, etc. Of course, there are also multi-line winding, which is more difficult for internal winding and is more prone to wire damage and breakage. The configuration requirements for the machine are also higher. 
 

In fact, whether it's a flyline winding machine or a needle-type winding machine, there is no significant difference between single-line winding and multi-line winding. It's just that the difficulty of winding and customer demands vary. The above has provided a simple explanation. We hope these little pieces of knowledge can be helpful to everyone!
