After dropping or dipping, the paint needs to be cured quickly. The existing curing oven is designed roughly, a stator winding is hung in the curing oven, and the temperature in the curing oven is raised to cure paint. Because the paint has fluidity before curing, the stator winding paint cured by adopting the method is easy to cause the phenomenon that the paint is unevenly distributed and the local paint layer has too small thickness or even no paint coating due to the flowing of the paint due to self weight. The novel stator winding paint curing oven adopts a process of simultaneously performing stator rotation and revolution in the curing process, can avoid paint concentration in the curing process, keeps uniform distribution of the paint, and improves the paint curing efficiency and the curing effect. However, the heating and temperature rising mode of the traditional curing oven still has the problems of uneven temperature, large temperature gradient and the like in the oven body. Therefore, in order to meet the new curing process requirements, a heating system suitable for the new stator winding paint curing oven needs to be designed.
