Description

Technical Field

[0002] As a core power equipment in industrial automation, new energy, and power transmission, the reliability and service life of electric motors directly affect the operational stability of downstream systems. The stator, as the core stationary component of the motor, undertakes the key functions of electrical energy conversion and mechanical energy transmission. Its outer shell (usually made of metal) is exposed to various environments such as humidity, salt spray, and chemical corrosion for a long time, which can easily lead to oxidation and corrosion, resulting in a decrease in surface insulation performance, a reduction in structural strength, and even the risk of short circuits or failures. Therefore, efficient and uniform protective painting treatment on the stator surface to form a dense and weather-resistant paint film has become an indispensable process in motor manufacturing.

[0003] To achieve a more uniform and high-quality painting effect, existing stator painting equipment typically employs complex mechanical structures. Consequently, these devices involve a large number of integrated sub-modules, resulting in higher production, usage, and maintenance costs. Furthermore, due to their complexity, these motor painting equipment often cannot be well integrated with motor production lines. Additionally, manual intervention or handling is required during painting and transfer, which not only reduces motor production efficiency and stability but also increases production costs.
