Same on the outside – better on the inside!

Exchange your old motor for 70 % more efficiency

During the development of the iQ-motor, our engineers took giant strides towards reducing energy

costs and fulfilling environmental protection requirements. By integrating ebm-papst EC technology,

new iQ-motor now features far better efficiency and pays for itself quickly due to its significant

energy-savings.

The best part of all: from the outside, it is the same old fan. The identical dimensions and mounting

options enable simple replacement without changes, structural modifications or any other extra

effort. Axial impellers with diameters of 154 to 254 mm can be installed on the new iQ-motor just

as before. The same applies to the mounting flange, the wall ring and the guard grille. Therefore,

thousands of applications can easily be made more energy-efficient as part of routine maintenance,

and may benefit at once from a drastic increase in efficiency, without any development effort.

The best equipment – not just in an emergency

Of course, the enormous increase in energy efficiency is not the only feature we have packed into the

intelligent motor. Important electronic features ensure that the iQ-motor works even more “conscien-

tiously” than its simple counterpart. For example, the motor has a closed loop speed control that

keeps it at the same speed at all times, regardless of the diameter of the installed blade. With dirt or

other interference factors, they do not cause an overload of the motor. The iQ-motor continues

working at reduced speed.

One design – thousands of applications

Just one design is compatible with the entire range of impellers, from 154 to 254 mm. This makes

logistics easier and keeps your development effort low. Moreover, the smallest size, the iQ 3608, is

the most compact version of an EC motor for its field of application in refrigeration. It has an axial

installation depth of only 74 mm, thus guaranteeing the necessary little bit of air in very tight

installation spaces.

Energy-saving and quiet – throughout its long service

All variants share the low-noise performance and the famous long service life that have made this

motor type so popular for so long. A critical role is played by a particularly low-friction bearing

system with double ball bearings. Thus the iQ-motor can continue to yield its enormous savings

potential for a very, very long time after only a brief amortisation phase. Available options include

the IP 54 type of protection and, of course, a standards-compliant TÜV approval.

Typical of ebm-papst: we have taken a standard motor and a principle that for decades has enjoyed

success in countless applications and made it more intelligent, energy-efficient and environmentally

friendly! Features of the shaded-pole motor (Q-motor) such as outstanding running smoothness, low

maintenance and a long service life have made asynchronous motors a standard component in small

fans. Our objective was to significantly improve the inner mechanism of the Q-motor by incorporating

EC technology – while keeping the exterior design identical. Conventional Q-motors can now be

replaced with the new “iQ”-motors if the fans fail or if a more energy-efficient solution is required.
