Unlike the AC motors used in ovens, air fryer motors have unique requirements, which DC brushless motors perfectly meet:
High speed and instant response: Air fryers need to generate powerful spiral hot air instantly. DC brushless motors can easily reach speeds of 10,000 to 20,000 revolutions per minute or even higher, and can quickly start, stop, and change speeds for precise control of airflow and temperature.
High efficiency and energy saving: Compared to traditional brushed motors, brushless motors use electronic commutation, resulting in less loss and higher efficiency. This means they can drive a larger airflow with less power (typically between 20W and 50W), saving more electricity.
Long lifespan and low noise: Without physical brush friction, sparks and wear are avoided, resulting in a lifespan of thousands of hours. Simultaneously, the mechanical noise is low, with only the sound of airflow, providing a better user experience.
Compact and integrated: DC brushless motors have a compact structure and high power density, making them ideal for integration into the limited space at the top or back of the air fryer. Intelligent Control: Easily connects to a microcomputer motherboard for programmed control, such as automatically adjusting fan speed and intermittent operation based on different recipes.
Key Features of an Air Fryer Motor: Besides the core feature of "DC brushless," it must also possess the following characteristics to withstand harsh working environments:
High-Temperature Resistant Design: The motor is located close to a high-temperature heating element, operating in temperatures exceeding 80-100℃. Therefore, it utilizes H-class (180℃) insulation materials and high-temperature resistant bearings and magnets.
Sealing and Grease Prevention: To prevent grease vapor generated during cooking from entering the motor, the motor shaft has a special sealing structure (such as an oil seal).
Aerodynamic Impeller: The motor does not operate independently; it directly drives a precisely designed fan blade. This fan blade is typically made of high-temperature resistant nylon or metal, and its shape is CFD-optimized to generate a uniform, concentrated spiral column of hot air, rather than simple blowing.
