How to Do Slotless Winding With Semi-automatic Fully-automatic Way WIND-BLDC
Slotness Winding Machine Application:
Ultra-light weight, fast response and high efficiency Coreless motor
Permanent magnet DC motor with coreless winding
Coreless(DC)- Slotless(EC)

Slotless Winding Consist of 4 machines with below function and process
1. Automatic winding
2. Hot press flattening
3. Pre-forming
4. Round forming
In which the most challenging processes are not winding itself,
but the subsequent hot pressing, round forming(upper/lower corner-forming) process
which ultimately determine the dimensional accuracy and motor performance.
Winding method and winding process can be widerly applided to handle below windings
1. Straight winding
The winding process forming a concentrate winding process
Winding process, enameled wire first wound on a forming mold according to the required turns,
And then shaped into a full winding on a wire-laying mandrel,
Adhesive is applied at both ends to solidify the coil structure
2. Slanted Winding (Concentric)
This method features wires tilted at a certain angle relative to the armature axis
This design allows continous winding, improving coil density and magnetic performance
3. Saddle Winding
Question and Answer:
1. What is the winding cycle time of below brushless motors?
2. Do we need to use electrostatic coating of the slots in order to use your machine?
Below samples and drawing are needed for machine manufacturing and commissioning:
1. CAD drawing of stator lamination for checking slot filling rate
2. Winding diagram
3. Copper wire 1 roll enough for winding 2pcs stators
4. Does the stator have positioning slotting place
