control circuit board

This circular BLDC fan driver board is specially developed for small household ventilation appliances. Adopting annular PCB layout with central shaft hole, it can be embedded inside the motor perfectly. Equipped with sensorless FOC vector control algorithm, it realizes stepless speed regulation with ultra-low noise and high energy efficiency.

Built-in multi-protection circuits (blocked rotor, over-current, over-temperature, reverse connection protection) ensure long-term stable operation. It supports OEM & ODM customization on voltage, speed gears, communication interface and size, widely compatible with circulating fans, air purifiers, cooling fans and ventilation equipment.
