The formula for the overall efficiency of turbocompressors

The higher the overall efficiency of a turbo compressor, the less electrical energy it needs to do the same work, but the efficiency of each individual component is crucial.»

Top banana in terms of performance thanks to an EC motor

Tropical Argentina SRL is truly passionate about fruit! The company is based in Buenos Aires and stores bananas and many other fruits in special ripening tunnels before shipping them to supermarkets and distributors. For the first time, they decided to use energy-efficient EC technology from ebm-papst to equip the latest system it had planned and built.»

Retrofit in the supermarket: cool for the climate

The DFI Retail Group wants to drastically reduce its energy consumption and has launched a huge retrofit project in its approximately 1,000 supermarkets and grocery stores in Hong Kong: 10,000 of its older ventilation drives have been replaced by energy-efficient EC motors.»

Busy helpers in the shipping center

ebm-papst is using a clever automation solution to make its shipping logistics more efficient and less burdensome for its employees.»

Cooling for the future of electromobility

Range and charging times are important parameters for electric vehicles. This is why fast charging processes are becoming increasingly popular and high-performance cooling concepts are required. They need to be well integrated and work reliably for a long time, even under harsh conditions. »

“Big performance for big fans”

The DV280 is the most powerful of the fan drives provided by ebm-papst. Rainer Müller, responsible for the engines mechanics, presents the new powerhouse.»

Powerful motors for big fans

Fan impellers with diameters of one or two meters are often driven by AC motors. However, by the time the next stage of the Ecodesign Regulation for fans comes into force, many of these solutions will no longer meet the increased requirements. The suitable alternative will then be new high-performance EC external rotor motors that operate at high efficiency levels. »

Vegetables from the glass box

In St. Georgen, the soon-to-be mechatronics and electronics technicians are working on the future topic of vertical farming. Fresh vegetables for the canteen are now growing in the indoor farm they designed themselves – thanks to ebm-papst components.»

What The Tech: How do air filter systems provide clean air?

Understanding the basic principles of air filter systems is key to develop better and more efficient ways to provide clean air. But how do you clean air? And what does clean air actually mean? »

What The Tech: Higher efficiency = better performance?

Does higher efficiency also mean better performance? Not necessarily. Ultimately, it depends on the application and installation location of axial and centrifugal fans.»

What The Tech: What is the difference between internal and external rotor motors?

There are different motors and in this video we look at the difference between internal and external rotor motors.»

What The Tech: How does an electronically commutated EC motor work?

What are the differences between an electric motor with an alternating current (AC motor) and an electronically commutated EC motor and what are the advantages? »

What The Tech: Is an EC motor more energy efficient than an AC motor?

When we compare an electronically commutated motor with an electric motor driven by an alternating current one thing becomes evident: The EC motor has a greater energy-saving potential.»

What The Tech: The importance of frequencies for high-performance fans and motors

Why does a fan need a frequency converter? Why is it important? And how does it work?»

New energy label for electrical appliances

Since March 2021, a new energy label with much more stringent specifications has been in force for many electrical appliances. The first devices to be affected are household appliances such as washing machines and dishwashers. As a pioneer of EC technology and as a development partner, ebm-papst can help manufacturers to bring their devices into the higher efficiency classes. »

Ahead of time with the EC motor: More efficient, quieter, smarter

Fan technology has developed very rapidly over the past 50 years. This would not be possible if you didn’t look at the big development picture: ventilation connections and therefore the perfect interaction of motor technology, electronics and aerodynamics. ebm-papst has been a key part of this evolution.»

Automation to get there faster

A motor passes through several optimization loops until it meets the required specifications. This used to cost a lot of time. Today, programs automate the work processes during development. And customers get a better product faster.»

Customized drive solutions for medical equipment

Medical equipment places high demands on the drive technology used in it. For these reasons, combining a variety of different modules to create customized drive solutions is a useful approach.»

The formula for current harmonics

Current harmonics are a burden for the power grid and the budget. Instead of going to great lengths to reduce then, it is best to avoid them altogether.»

The formula for the residual circuit breaker

A fault current’s waveform is crucial to the selection of the
right residual current circuit breaker – also for EC motors.»
