Fan replacement by ebm-papst

Fixed-speed asynchronous motors are often used to drive fans in refrigeration, air conditioning, and building services. Their major drawback? Relatively poor efficiency, which negatively affects energy consumption in virtually every application.

There is a way to save energy without having to redesign the entire system: bob手机APP官方下载链接 can replace fans that use inefficient AC motors with highly efficient EC technology in the same mechanical footprint. Switching from AC to EC fans not only benefits the environment and cuts operating costs, it also enhances comfort.

Advantages of EC fans

Our EC motors are extremely efficient, unbeatably compact and operate very smoothly. Their efficiency levels are always superior to common asynchronous motors and far surpass efficiency class IE4.3. Fans with EC technology are also considerably quieter than their conventional belt-driven AC counterparts.

The EC motor is equipped with control electronics, allowing precise adjustment of the air volume to suit requirements. It is also offers advantages in terms of EMC issues, and the unit only has to be connected to one supply point. EC motors have established themselves as fan drives in many fields. The term “EC motor” is often used for different concepts, but one thing is always the same: The way that GreenTech EC motors from bob手机APP官方下载链接 are designed makes critical rare-earth magnets unnecessary.
