From Q to iQ. Quadratic. Practical. Intelligent

in Motor
  • We have taken a standard Q-motor and a mechanical principle that have been used for decades and made it more efficient.
  • We have made this efficient solution fit the existing application by replicating all possible mounting arrangements with an intelligent motor that will give the air flow required.
  • We have ensured that the motor is protected against moisture to stop premature failure.
  • We have ensured smooth bearing systems to ensure long life time.

With the new iQ motor, ebm-papst has broken the barrier restraining engineers from improving efficiencies in existing refrigeration equipment.

In developing the iQ motor - permanent magnet motor (PMM)  we have taken giant strides towards reducing the energy costs, lowering waste heat and fulfilling the environmental protection developments. Integrated EC technology has significantly increased the overall standard of a motor technology; the new iQ - motors achieve greater levels of efficiency resulting in shorter and shorter payback periods both for the end user and the environment.

From Q motor to iQ motor: Same on the Outside - Efficient on the inside.


It pays to switch

Switching over to the new motor technology is worthwhile whenever an old shaded-pole motor should be replaced or energy-savings are desired. The switch to high efficiency refrigeration motor pays off for both the environment and the user, as this shows: 
In a small supermarket, 200 fans are used that have 200 mm impellers and a 34° pitch.

+ The energy savings is 70%, which corresponds to 37.5 MWh per year.

= For the environment, this value means that 22 fewer tonnes of carbon dioxide.

= For the user there are profits as well: assume an electricity price of 0.18$ per kWh, then save 6750 $ a year.

An analysis of EC fans for refrigeration applications shows: The operating costs of a Q motor are the unknown and hidden costs – these massively outweigh the initial capital cost outlay. A standard AC motor has a capital cost of 6% of its whole life costs, the remaining 94% are spent on operating costs. With an AC Q motor, the capital costs are 11%, but the operating costs are reduced to only 34%. This means savings of 55%.

Moving to high efficiency motors gives life time savings. The longer the life of these savings the better it is to the bottom line.

ebm-papst A&NZ Pty Ltd


We are the leading global manufacturer and supplier of fans, blowers and air moving products. We provide a unique range of air movement or specialist drives products. Our motor technology, engineering and logistics expertise will add value to your business.

ebm-papst A&NZ Pty Ltd was formed in December 2005 following separation from long-time partners. Since then, ebm-papst has grown and developed, and is now situated in a new head office in Laverton North, Melbourne, with offices in Sydney and Auckland.

Our products and innovations are developed in three main manufacturing and development centres, namely: ebm-papst Mulfingen (formerly ebm), ebm-papst St. Georgen (formerly PAPST) and ebm-papst Landshut (formerly mvl). At ebm-papst A&NZ Pty Ltd, we develop fan, motor and control solutions for the following applications:

  • Refrigeration
  • Air-conditioning
  • Heating
  • Ventilation
  • Electronics
  • Telecommunications
  • Bio medical
  • Automotive
  • Sensors and actuators
  • Prime movers

In order to achieve an aerodynamically optimum shape for our fans, we design fan blades, impellers and ducted housings to fit the application environment. From seemingly small details, such as the bladetip slip with winglets, we can achieve significant noise reduction with even higher efficiencies. We combine our expert drive engineering and aerodynamics with intelligent electronics for optimal efficiency, creating system solutions that work.

A concern for the environment underpins all that we do at ebm-papst A&NZ Pty Ltd. We have adopted the GreenTech philosophy and are committed to creating products that are sustainable and environmentally responsible. The GreenTech idea reflects our simple company principle: "Each new product that we develop has to be better than its predecessor in terms of economy and ecology." Year after year, we commit our knowhow and inventiveness to redefining standards with ever more powerful and efficient motors and fans that raise the bar ever higher.

By signing the Kyoto protocol Australia has followed New Zealand and committed its future to tackling climate change and global warming. ebm-papst has been addressing these issues globally and now supplies 36% of its turnover with EC or high efficiency, speed controllable motor technology.

Ultimately, the efficiency of GreenTech is measurable. For example by satisfying the strictest limits for energy-powered products that the EU has passed to date. These planned limits are not scheduled to come into force until 2015, but our EC fans already exceed them by far.

Moreover, we are pleased that our entire production chain regularly stands up to the scrutiny of environmental specialists. Awards such as

  • AIRAH Awards of Excellence
  • arbs Industry Awards - Refrigeration Product Excellence
  • arbs Industry Awards - HVAC Product Excellence
  • Cool World Industry Awards - Winner Excellence Award
  • Cool World Industry Awards - Green Innovator of the Year

clearly show that we can live up to our own high standards.

ebm-papst A&NZ Pty Ltd is committed to supporting manufacturers in Australia and New Zealand with innovative products and added value such that they can prosper in increasingly turbulent global markets.
