What Is A BLDC Fan And How Does It Work?
A BLDC (Brushless DC) fan is a type of electric fan that uses a brushless DC motor to rotate the fan blades. Unlike traditional fans that use a brushed DC motor, BLDC fans use a controller to regulate the speed of the motor, which provides more efficient and reliable operation. The controller uses a sensor to monitor the motor’s speed and adjust the voltage and current supplied to the motor accordingly.
The use of a controller in a BLDC fan allows for more precise control over the motor’s speed, which enables features such as variable speed control, soft-start, and overcurrent protection. This makes BLDC fans more energy-efficient and quieter than traditional fans.
