EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds. Today we will give you a brief introduction of EC fans.

What is an EC fan?

An EC fan refers to a centrifugal fan that uses an EC motor as power, and an EC motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction.

It is a powerful device that can convert electrical energy into mechanical energy. The fan is a mechanical device that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine.

Advantages of EC fans

Good speed regulation performance

The EC fan is particularly convenient to operate, with low noise, and basically controls the speed through the back electromotive force, the speed error is smaller, and the complete stepless speed change can be realized.

High efficiency

The EC fan adopts a permanent magnet brushless structure, replacing the traditional brushed alternating induction drive, which makes the motor more efficient, more energy-saving and environmentally friendly.

Long life span

All the control circuits and other electronic devices of the EC fan are embedded in the fan with built-in AC-to-DC, and DC-to-AC inverter modules, which make the fan life longer and more stable.

Higher conversion rate

As a three-phase AC permanent magnet synchronous external rotor motor, the EC fan breaks the weight limit of the traditional AC motor and makes the energy conversion rate higher.

High stability

The components of the EC fan are more suitable, making the fan more stable, less vibration, less noise, and willing to work continuously and uninterruptedly.
