The more commonly used brushless cooling fans are divided into EC, DC, AC, etc. Among them, EC fans are DC fans, and EC cooling fans convert AC to DC. In addition to DC voltage power supply, AC voltage can also be used for power supply. The voltages of 12V, 24V, 48V, 110V, 220V, 380V are universal, without conversion.

1. The EC fan breaks the frequency limitation of the traditional AC fan, and can greatly accelerate the operation speed of the fan. The lightweight motor design can reduce the air outlet area.

2. The EC fan motor is equipped with an intelligent control module DC brushless and maintenance-free type. Its advantages are high efficiency, energy saving, long service life, small vibration amplitude, low noise, and continuous uninterrupted work.

3. The structure of the EC fan is simplified, which not only improves the manufacturability of the motor, but also enhances the mechanical reliability of the motor's operation, greatly improves the air gap magnetic density, makes the motor achieve the best design, and reduces the size of the motor.

4. The EC fan supports a variety of speed control and other functions, such as PWM, TC, VC temperature control, which is very energy-saving, and can output various signals to detect the running status of the ventilation cooling fan in real time.

5. The EC fan is capable of high power and comes with a soft-start function. Its starting current is small, and its impact on the power grid and equipment is also small, so the reliability is very high.
