What Is an EC Fan?
An EC fan, short for electronically commutated fan, is a fan that adjusts motor speed through inverter control.
By varying the motor speed with an inverter, the airflow and noise level of the fan can be adjusted. EC fans find applications in various fields such as household appliances, industrial equipment, and automobiles. In household appliances, they contribute to energy efficiency and noise reduction, while in industrial equipment, they aid in controlling server temperatures. In automobiles, they improve cooling efficiency and suppress engine noise. The realization of energy savings and improved noise levels has led to increased demand across different sectors.
There are different types of fans, including axial fans, propeller fans, and radial fans, chosen based on their intended use. The structure of an EC fan consists of three main components: the inverter, the motor, and the fan. Its notable feature is the precise adjustment of motor speed through inverter control.
