With the rapid growth of healthy cooking trends worldwide, air fryers have become a core product category in household kitchen appliances across Europe, North America, Southeast Asia, and the Middle East. Air fryers rely on high-speed hot air circulation systems to achieve oil-free cooking, where the fan motor system plays a critical role in airflow efficiency, temperature uniformity, thermal stability, and overall product lifespan.
The customer in this project is a mid-to-high-end kitchen appliance manufacturer focused on OEM/ODM air fryer production for international markets, including retail chains and cross-border e-commerce platforms. The customer required a stable, cost-effective, low-noise, long-life AC motor solution with high reliability for continuous operation in high-temperature environments.
BG Motor (Ningbo BG Motor Co., Ltd.) was selected as the motor solution provider to develop a dedicated fan motor system based on a 61mm shaded pole motor platform for the new-generation air fryer product line.
High-temperature resistance
Continuous operation under hot air circulation requires high thermal endurance of winding insulation, bearing systems, and magnetic components.
Continuous duty operation (S1 duty)
The fan motor must support long-duration operation without performance degradation, overheating, or speed instability.
Low noise & low vibration control
Household appliance standards require strict noise level control, especially in high-speed airflow systems.
Compact structure & integration
Limited internal installation space demands precise dimensional control and structural optimization.
Cost-performance optimization
The solution must balance performance, durability, and mass-production cost efficiency for large-scale manufacturing.
Supply chain stability
Long product lifecycle requires stable motor supply capability and consistent batch quality
