Welding is a very important process in the winding process of motor products. Welding is a very important link, whether it is the forming winding or the dispersing winding, whether it is the connection between the winding and the lead wire, or the connection between the main line in the winding. In the analysis and treatment of faulty motors, it can be found that the electrical failure caused by poor welding quality is not uncommon.
Different motor manufacturers have different processing processes for this link, but the principle of processing is roughly the same, that is, the insulation layer of the magnet line itself is cleaned first. No matter be enameled wire or winding wire, this link is more troublesome. Yes, especially in the case of multi-turn parallel windings, the electromagnetic ratio itself is difficult to clean the insulation. Some manufacturers use scraper, some manufacturers use chemical methods, but no matter which, the efficiency is very low, and more serious is that when the insulation layer of the magnet line is not completely processed, the welding effect will be very poor. The semi-finished inspection and factory test of the motor may not expose problems, and the motor is more prone to failure in the process of operation.
In order to solve this problem, professional welding equipment came into being. In the process of welding, the equipment adopts high temperature heating to clean the insulating layer on the electromagnetic wire, and realizes the welding object melting into a whole through hot melting. Very efficient and reliable welding method. Automatic welding equipment mostly adopts inverter power supply technology and micro-electronic control technology, which has the advantages of accurate control, wide process adaptability, energy saving, high efficiency, stability and easy operation.
For large copper rod rotor motor windings, if welding has a good application effect. For most scattered winding and forming winding, automatic welding method is more. This is also the basis for improving the efficiency and quality of motor production and processing.
