What are the causes of wire breakage in the automatic winding machine for brushless motor stators?

The winding of the stator of a brushless motor is generally carried out using specialized automatic winding machines. Commonly used ones include flywheel external winding machines and needle-type internal winding machines. The two winding methods differ, but due to the existence of machine and human factors, sometimes wire damage occurs, resulting in poor product quality. So, what are the causes of wire damage in the automatic winding machine for brushless motor stators? How can we avoid wire damage? Now, NOYU will simply analyze this for you! Hope it can be helpful to everyone! 
 

The reasons for wire breakage in the automatic winding machine for brushless motor stators may include the following: 
Excessive winding speed: When the winding speed exceeds the specified limit, it is likely to cause excessive tension on the wire, which may result in wire breakage or damage. 
2. Insufficient or inappropriate wire diameter: If the wire material or wire diameter used does not meet the requirements of the equipment, such as being too thin or too thick, it may result in improper tension on the wire during winding, thereby causing damage to the wire. 
3. There are foreign objects on the wire terminals or burrs on the frame: These foreign objects or burrs may scratch the wires during the winding process, causing damage to the wires. 
4. The tensioner was not properly adjusted: Excessive or insufficient tension can both cause damage to the circuit. Excessive tension is likely to cause the wire to break, while insufficient tension may cause the wire to loosen during winding, thereby affecting product quality. 
To prevent the stator automatic winding machine for brushless motors from damaging the wires, the following measures can be taken: 
Follow the winding speed specified in the equipment manual or the winding speed recommended by the manufacturer strictly. Avoid using either too fast or too slow winding speeds. 
2. Use the appropriate type and size of cables that meet the equipment requirements, and ensure that the quality and specifications of the cables match those of the equipment. 
3. Regularly clean the nozzles and spools to ensure they are free from foreign objects or frayed edges, to prevent damage to the wires. 
4. According to the model and specifications of the wire, adjust the tension of the tensioner appropriately to ensure that the wire receives the correct tension during the winding process. 
5. Regularly check the operating condition of the equipment to ensure it is in good working condition and prevent damage to the lines due to equipment failures. 
6. Regular training should be provided to the operators to enhance their operational skills and safety awareness, thereby reducing the problems caused by human factors in wire damage.
