Same on the outside –
        Better on the inside!
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 axial 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.

A new standard for countless applications-

New ebm-papst iQ-motors have a maximum power output of 10 watts and are suitable for the following applications:

  • Pellet ovens
  • Vending machines
  • Compressor cooling systems
  • Underfloor convector heaters
  • Refrigerated display cases
  • General condenser applications such as bottle coolers
  • Industrial use (air cooling and transport)


    • Example:
    40 fans with an impeller diameter of 200 mm and 34° inclination are installed in a small supermarket. The annual savings potential of iQ-motors compared to conventional shaded-pole motors:

    Energy savings: 70% = 7.5 MWh Savings for the environment: 4.4 tonnes CO2 Cost savings: 800.00 €
    (at an assumed electricity cost of 10.7 Eurocent/kWh)

    The process of converting from a Q-motor to the new technology is extremely uncomplicated because the exterior design is identical. Axial impellers with diameters of 154 – 254 mm are mounted to the iQ-motor in the same way. The same applies to the mounting flange, the wall ring and the guard grille.
    The new generation of compact energy-saving axial fans

    In almost all spheres of life, energy savings have become an important issue by now. Our new and compact axial fans are based on the energy-saving motor (ESM) and offer high efficiency and thus considerable energy savings and improved service life at the same time - aspects which are definitely called for with refrigeration plants, such as refrigerated display cases or refrigeration chests or condensing units.

    The axial fan W1G 200 already established quite successfully on the market has now been complemented by the sizes 230, 250 and 300 mm. The new plastic rotor was optimised to meet improved aerodynamic criteria and makes these fans operate even more quietly. What is more, they environment benefits from the fact that no varnish needs to be used any more!

    Compared to conventional shaded pole motors, energy-saving motors are three times as efficient. Higher efficiency translates into less intrinsic heat generated during operation, with a reduced need to dissipate heat and putting a strain on the environment. This results in further energy savings, as less refrigeration capacity has to be applied in the first instance. The new and compact energy-saving axial fans, with an output power of between 5 and 20 W, can be easily connected via a plug-in connection. Moreover, the motor speed can be optionally set via programming interface. A second speed step - e.g. for night setback, can be realised via actuator input.

    The energy-saving fans are robust, maintenance-free and durable. Their service life is rated at more than 40,000 hours, equalling continuous operation of more than 4.5 years. As regards environmental impacts, their design complies with protection type IP 54 specifications. Optionally, protection type IP 65 is available. Moreover, these energy-saving axial fans comply with protection class 2.
