2. Function Description

The power supply voltage of GD32W515 Wi-Fi FOC Fan Control Solution is 12V, and the rated current is 2A. Double closed-loop control regulating speed and current using the advanced FOC algorithm can reach speed as high as 1500rpm. Additionally, the matching Wi-Fi fan can run smoothly in different gear levels.

GD32W515 Wi-Fi FOC Fan Control Solution with highly integrated hardware, is equipped with advanced timer TIMER0 and general timers TIMER1/2, which can simultaneously control a PMSM and two stepping motors. Additionally, the fan can be controlled by buttons and Wi-Fi together.
