Winding is a very critical link in the production and processing of motor windings. During the winding process, on the one hand, it should be ensured that the number of turns of the magnet wire meets the requirements, and on the other hand, the force of the magnet wire must be relatively uniform and appropriate to prevent the magnet wire from being thinned or broken during the winding process.

In the actual production and processing process, the electromagnetic wire is often deformed by force due to various factors such as the mismatch between the spool and the equipment, the spool is too heavy, the spool is damaged, and the winding equipment is stopped. Undesirable phenomena such as damage to the magnet wire insulation layer, all of these problems will lead to the performance of the winding not meeting the requirements, and ultimately have adverse consequences on the performance of the product.

In order to prevent the occurrence of such problems, during the winding process of the magnet wire, it should be ensured that the wires are neatly arranged and not scattered; the weight of the single axis should not be too heavy to prevent excessive tension or unevenness in the winding process; Adjust the matching relationship between the spool and the device to avoid sudden jamming during the winding process.

In fact, the seemingly simple problems in the winding process have not been paid attention to by the manufacturers, which will always lead to the occurrence of some inappropriate matters.

Magnet wire is an insulated wire used to make coils or windings in electrical products. Also called winding wire. Magnet wire must meet a variety of usage and manufacturing process requirements. The former includes its shape, specification, can work at high temperature for short and long-term, and withstand strong vibration and centrifugal force at high speed in some occasions, withstand corona and breakdown under high voltage, and chemical resistance under special atmosphere. Corrosion, etc.; the latter includes the requirement to withstand stretching, bending and abrasion during winding and embedding, as well as swelling, erosion, etc. during dipping and drying.

Magnet wires can be classified by their basic composition, conductive core, and electrical insulation. Generally, it is divided into enameled wire, wrapped wire, enameled wrapped wire and inorganic insulated wire according to the insulating material and manufacturing method used for the electrical insulating layer.

The purpose of magnet wire can be divided into two types: ① general purpose, mainly used in motors, electrical appliances, instruments, transformers, etc., to generate electromagnetic effects by winding coils, and use the principle of electromagnetic induction to achieve the purpose of converting electrical energy and magnetic energy; ② special purposes, It is used in fields with special characteristics such as electronic components and new energy vehicles. For example, micro-electronic wires are mainly used for information transmission in the electronics and information industries, and special wires for new energy vehicles are mainly used in the production of new energy vehicles.
