Stator winding is a necessary process in the production of brushless motors, most motor manufacturers use special winding machine equipment, but not all products winding are smooth, such as wound wire, broken wire, winding is not tight and other defects, will directly affect the performance and life of the motor, resulting in defective products. So what are the common problems of brushless motor stator winding? Vacuz briefly introduce it to you!

A. Stator winding is not tight, loose, bloated

1. The winding method is not well designed, including the width of the line, stator height, etc. is not well debugged.

2. Tensioner adjustment is not appropriate, the line is too loose.

3. Machine configuration problems, machine operation is not stable.

Solution: redesign the winding method, using a better configuration of the equipment, adjust the parameters, adjust the tensioner tension to the appropriate.

Second, the stator winding broken line

1. Tensioner tension is too tight, the strength is not appropriate, resulting in the winding process of the enameled wire broken.

2. Winding speed is too fast, more than the limited speed.

3. There are impurities and foreign objects in the wire wheel, wire nozzle, wool felt, etc., or there is a problem with the wire cylinder.

Solution: adjust the tension to the appropriate, winding speed should not be too fast, in the allowable range, clear the auxiliary accessories in the impurity foreign matter.

Third, the stator winding injury line

1. Mold design problems, processing is not careful enough, burrs, bumps, etc., polishing does not meet the requirements.

2. Machine debugging is not in place, inaccurate positioning, resulting in scraping when winding. There is also the problem of wire mouth and auxiliary parts.

Solution: Check the auxiliary spare parts to ensure that the mold production and processing meet the requirements, accurate positioning, machine adjustment and each parameter is reasonable.

The above is the brushless motor stator winding common problems and solutions, master these tips, help to better understand the winding process and procedures to ensure that the winding meet the requirements.
