Industrial exhaust fans, widely used in diverse industrial settings, swiftly exhaust impure air, heat, moisture, dust, smoke, and harmful gases. This enhances indoor air quality, creating a comfortable working environment. The market size of industrial exhaust fans in China has exceeded 60 billion yuan, and the growth rate is expected to remain above 10% in the coming years. 

The MCU serves as the core of the motor in industrial exhaust fans, directly influencing the system's functionality and cost control. While sensorless FOC control dominates the market, there are challenges such as excessive noise, less than 100% startup success rate, and startup shaking and flipping.

Geehy's APM32F035 industrial exhaust fan mass production solution enhances the sensorless Field-Oriented Control (FOC) method, delivering remarkable efficiency, minimal noise, and seamless operation across all speeds. It excels in initial position detection, boasting an exceptional 100% startup success rate.
