What is an EC fan？

EC fan is a new breed in the fan industry. They are different from other DC fans. They can not only be powered by DC voltage, but also can be powered by AC voltage. Voltage from DC 12v, 24v, 48v, to AC 110V, 380V,They are not needed to add any inverter conversions.
EC motor is a DC brushless maintenance-free motor with built-in intelligent control module, with its own RS485 output interface, 0-10V sensor output interface, 4-20mA speed control switch output interface, alarm device output interface and master-slave signal output interface. EC fans have the characteristics of high energy saving, high efficiency, long life, low vibration, low noise and continuous uninterrupted operation, etc. The brushless DC motor is greatly simplified in structure because the collector rings and brushes for excitation are omitted. At the same time, not only the manufacturability of the motor is improved, but also the reliability of the machine running the motor is greatly enhanced and the service life is increased. At the same time, the air gap magnetic density can be greatly improved, and the motor index can be optimally designed. The direct effect is that the motor volume is reduced and the weight is reduced. Not only that, it also has excellent control performance compared to other motors.
