The causes of wire breakage in automatic BLDC motor stator coil winding machine

Semi-automatic winding machine is the most common winding machine used in China, which can only achieve self-layout, and the rest of the process needs to be done by operators. Usually the number of spools is small to assist the operator’s process time and facilitate the replacement of different molds to manufacture different products. Because of the low price, certain processes that cannot be completed by mechanical equipment can be completed by human labor, and deviations in the machine and equipment can be adjusted by the operator to make up for them, making it easy to replace the product. The fully automatic winding machine, with the help of electric motors, electric components, pneumatic components, transmission devices, sensors, control systems, etc., can constitute a machine and equipment with a high level of automation technology. Usually, it can arrange the wire, wrap the head, break the clip wire, twist the wire, and load and unload by itself. The operator just needs to ensure that there is enough raw material to ensure continuous production by replacing the wire immediately when there is no product workpiece or copper wire, and the number of spools is usually high to achieve efficient manufacturing. Machines and equipment with a high enough level of automation technology can achieve the need for one employee to look after several machines and equipment together.

With the rapid development of the electric motor industry, the electric motor equipment has become more and more popular, such as the automatic winding machine, which is a special stator-rotor winding machine, and the traditional human method, not only improve the speed and efficiency, but also the number of turns will not be wrong, and the quality of the winded coils is better.

In the process of operation, there will always be points of failure, such as broken wire, then we know what is the problem?

1. It is likely that the tensioner induction part of the problem, check the tensioner induction switch is not normal, if there is a problem to adjust.

2. Setting problems, it is likely that the tension setting problems, not in accordance with the corresponding tension table to complete the calibration, the size of the wire specifications do not pay attention to the corresponding, and then there is the rate set too fast.

3. The winding method and the specific location of the point, and the mold shell does not correspond well, there is a corresponding deviation, it is also likely that the frame is not standard, the diameter size is not equal, the slot distance is not consistent. Attention is in the case of processing mold, must be polished and polished after, not to have burrs, burrs, etc., otherwise it is very easy to scrape off the line.

4. wire problems, different wire parameters have corresponding differences, copper wire, aluminum wire, iron wire respective hardness is all different, before the application must be clearly divided.
