Stator bars are crucial components in motor production. The traditional process used for curing the surface paint of stator bars has a long cycle, low efficiency, and high energy consumption. Infrared radiation curing is a method that can potentially overcome these issues. This study investigated the curing behaviors of three types of paints (low-resistance, high-resistance, and red enamel paints) on the surfaces of stator bars under infrared radiation. The paint samples were prepared using an epoxy glass cloth plate as the substrate material and a silicon carbide infrared radiation plate as the infrared radiation source. The cured paint was characterized via infrared spectroscopy and scanning electron microscopy. The degree of curing and the electrical properties of each sample were measured and compared with those obtained using the traditional curing process. The results indicated that the degree of curing of the three types of paints after curing by infrared radiation was higher than that under the traditional curing process by 8.98%, 10.33%, and 10.40%, respectively, and that the surface drying effect could be achieved in 2 min. The electrical properties and surface morphologies of the paints were shown to satisfy the standard performance requirements. The paints cured by infrared radiation exhibited good electrical properties. The study thus demonstrated the high efficiency and practicability of the infrared radiation curing method, as well as its wide potential applicability.
