The two main solutions for brushless motor winding: flying fork winding and needle winding, which have different application characteristics and winding requirements for different stator types. So how about the specifics, Vacuz will give you an introduction! Hope it can help you!

First, flying fork type winding

1.Applicable scene

Slot to the outside of the motor stator, such as aeromodelling motors, balance car motors, scooter motors, new energy vehicle motors and so on.

2.Working principle

The flying fork rotates at high speed to drive the copper wire winding, the guard plate assists to snap the copper wire into the slot, and the die head moves back and forth to realize the orderly row of wires.

3.Features

Fast winding speed: greatly improve the production efficiency.

High precision: Ensure the uniform distribution of copper wire in the stator slot, improve the stability of motor performance.

4. Winding requirements

Debugging: the position between the die head, die tongue, stator pole and guard plate should be debugged and positioned accurately to avoid offset, skipping, broken and injured wires.

Needle winding

1.Applicable Scenario

Slot inward motor stator, such as power tools, pumps, stepper motors, vacuum cleaner motors.

2.Working principle

After setting the parameters, the tungsten steel wire nozzle moves with the wire, and the guide needle moves up and down and back and forth to realize the precision lining and winding.

3.Features

High flexibility and applicability: it can be adapted to various types of motor stators, realizing multi-layer winding and complex winding trajectories.

4.Winding requirements

Commissioning: Pay attention to the position and positioning between the wire arrangement device, needle bar, wire nozzle, stator skeleton and mold to avoid hitting the needle, the way of alignment needs to be reasonable and simple, and the alignment meets the requirements, there can’t be any broken or injured wires.

For the stator with the slot facing outward, when using the flying fork winding equipment, the position between the mold head, mold tongue, stator pole and guard plate should be adjusted accurately to ensure the winding quality.

For stator with slot facing inward, when using needle winding equipment, it is necessary to pay attention to the position and positioning between the wire arranging device, needle bar, wire nozzle and other components to ensure the stability and accuracy of the winding process.

Ordinary stator winding, winding requirements in general, the use of conventional equipment can be completed after the completion of the salt water test to ensure product quality.

Stator precision wiring, high requirements for spare parts, servo motors and drives, etc., it is recommended to use high configuration equipment, debugging needs to be careful to ensure that the line is not messy.

Stator coarse line, commissioning speed needs to be slowed down, winding method as simple as possible, machine configuration should be good, salt water test is indispensable.

Multi-wire winding, wire diameter and number of strands, need to pay special attention to the configuration and winding method, the speed should not be too fast, to avoid injury to the wire.

What are the common solutions for brushless motor winding? What are the requirements for stator winding, Vacuz has made a brief introduction above, I hope this little knowledge can help you!
