AC or EC motors? Compact fans? Planetary gearboxes? These and other questions from the ebm-papst universe are explained in the “What The Tech?!” videos.
A series for inquisitive people, for technology enthusiasts or anyone who also wonders why not all motors are the same and what requirements our changing world has for the technology of tomorrow.
Every two weeks, there will be a new, exciting explanatory video from the world of air and drive technology.
Predictive maintenance helps to ensure a long service life for fans. How exactly does this work, and how do you get the necessary data?»

Expanding cities need space to grow food. And that is exactly what is dwindling as the population grows. Could vertical farming be a solution for this problem?»
Both direct current (DC) and alternating current (AC) describe types of current flow in a circuit. Both are essential to enable the functioning of our electronics, but do you know the difference between direct current and alternating current?»
When you process a lot of data, you need data centers. But that much data can really make the system overheat. It takes a lot of cooling and a lot of money to pay for it. So is there a cheaper, less energy-intensive way to keep your hot data cool?»
Due to climate change, electromobility is becoming increasingly important, the number of electric vehicles is also increasing rapidly. Therefore, it makes sense that the electricity used for them should come from renewable energy sources. But what kind of renewable energy sources do we have and how important are wind power plants?»
When do installation errors occur? And which parameters should be considered when installing fans? Here you will learn more about the installation parameters of fans and what to consider.»
A heat pump provides heat, but is also capable of cooling your home. It transfers heat from one place to another by different air or heat sources. Find out about the exact working principle of a heat pump here.»
Does a stepper motor or a servo motor suits the needs of your application best? And what are exactly the differences between a servo motor and a stepper motor? Lets find it out together.»
When space is limited, there is often no other solution: A compact fan that takes up little space and still delivers the necessary performance is needed.»
Of course, planetary gears don't drive planets. It's called that because like in our solar system, everything revolves around the sun gear, the drive at the center.»
This video explains the working principle of brushed motors and brushless motors.»
Minimize the wear, noise and energy consumption of your ventilation system by using the FanGrid technology.»
Resonance is key for a smoothly operating fan. But, unfortunately, resonance can cause damage. That's how fans can handle resonance and vibration.»
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? »
Does higher efficiency also mean better performance? Not necessarily. Ultimately, it depends on the application and installation location of axial and centrifugal fans.»
There are different motors and in this video we look at the difference between internal and external rotor motors.»
Why does a fan need a frequency converter? Why is it important? And how does it work?»
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 are the differences between an electric motor with an alternating current (AC motor) and an electronically commutated EC motor and what are the advantages? »
