摘　　要：静电喷涂电机槽绝缘技术在民用电机自动化生产线上已大量成功应用。由于涂层厚度较厚(厚度大于0.3 mm)及涂层耐温度冲击性能未知,因此在槽满率较高及应用环境温度跨度较大的场合应用受限。本文通过对喷涂过程的工艺参数、涂层厚度(端面与槽内)的均匀性、涂层固化参数等进行工艺验证,得到了最佳工艺条件;并分析研究了电机应用该槽绝缘技术后,在环境试验中的绝缘电阻及涂层性能稳定,进而得出在大温冲下该涂层可作为电机槽绝缘应用。The electrostatic spraying technology for motor slot insulation is widely used in automatic motor production lines.Due to the thickness(over 0.3 mm)and the unknown temperature resistance of the coating,the application of the technology is limited when the slot filling rate is high and the ambient temperature span is large.In this study,the technical parameters of the spraying process,the thickness and evenness of the coating,and the curing parameters of the coating are optimized.The insulation resistance and stability of the coating are tested and analyzed,and it is concluded that the optimized technology can be applied for motor slot insulation under large temperature span.
