The most commonly used electromagnetic wire for high-voltage motors is SBEMB double glass fiber wrapped film wrapped flat copper wire and SBEFB self-adhesive double glass fiber wrapped mica tape wrapped copper flat wire. Each manufacturer will choose different heat resistance due to the difference of process methods and product features. Grade and different insulation thickness. Electromagnetic wire storage and protection are extremely important. The cleanliness, temperature and humidity of the storage environment are not enough, which will inevitably reduce the quality of the coil.
The enameled wire arrangement of the bobbin is not neat and even interspersed, causing the winding process to be jerked, causing the insulation of the electromagnetic wire to be displaced or damaged, and the insulation function is lowered. The enameled wire shaft is damaged, causing some of the wires to penetrate into the gap of the bobbin, and the insulation layer of the electromagnetic wire is severely damaged. Participated in the scene of the show and saw such a scene and the invisible embodiment of the operator.
Coil winding requirements: During the winding process, the stress is stable and the tension is even, ensuring that the enameled wires are placed neatly to ensure the quality of the final glue meets the requirements. Participating in the viewing site is mostly active winding machine. The problem that the electromagnetic wire was pulled hard and hardened should not occur. The operation of the preparatory link of the partial axis is not detailed enough, leaving a difficult life-threatening danger to the subsequent process.
Glue process control. The gelation process is a very important part. The gelation temperature should be suitable to ensure that the glue can be fully melted and saturated, and the coil is solidified into one whole. The actual problems in the gelation process: 1) The electromagnetic wire does not meet the requirements and cannot be gelatinized. 2) The storage and aging of the electromagnetic wire cause the quality of the glue to be not high or unqualified. 3) The gelation temperature and timing are not accurate.
