Put simply, DC motors are around 30% more efficient than AC motors because the secondary magnetic field comes from permanent magnets rather than copper windings. An AC motor consumes additional energy solely to create a magnetic field by inducing a current in the rotor. But this is only half the story. The use of modern electronics in controlling the motor has opened up many other possibilities which contribute to using less power.

AC motors are designed to operate at a certain point on their performance curve which coincides with their peak efficiency. Either side of this operating point, the efficiency can drop off considerably. EC motors on the other hand have an almost flat efficiency curve which varies relatively little across the speed range, a range which is not limited by synchronous speeds or as susceptible to voltage fluctuations as an AC motor. This makes the EC fan much more flexible in terms of being able to use the same product to match the performance requirements of different applications while still benefitting from increased efficiency.

 

The available range of AC input EC fans is expanding all of the time. There are axial and centrifugal fans, forward curved and backward curved, single inlet and double inlet, single phase and three phase and they are often directly interchangeable with their AC equivalents. EC offers the OEM more than just energy-efficiency. It is an opportunity to bring new technology and functionality to their products. With ever-increasing demand for energy efficient systems, when it comes to fan based products, there’s no reason for manufacturers not to have any in their portfolio.

 

Permanent-magnet brushless DC motor within the rotor
The stator is driven by electronic switches (which replace the Carbon brushes), controlled by a microcontroller.
Electronic system (hall effect sensor or software is used to recognize the rotor position)
AC operated (230Volts Single phase or 380/480Volts 3phase, 50/60Hz)

How do I know which model I should choose

Please tell us the fans pressure and ofan and size of fans’ diameter you need. We will study and suggest you the right model.

 

 if the fans doesn't work well, what shall I do ?

If happens within one year, we will take in charge of the maintenance, or send you a new machine freely.
