What the Tech!? Video knowledge by ebm-papst
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.

What the Tech: Ventilation systems for air exchange according to demand
Air exchange is absolutely necessary with insulating windows in order to regulate air humidity. This is possible with centralized and decentralized ventilation systems.»
What the Tech: What are the casic components of an electric ventilation system?
For a flow machine to be able to generate air flow, a fan needs a number of important components. No matter whether an axial, centrifugal, diagonal, or tangential impeller is used, the fan is driven by an electric motor.»

What the Tech: How will a retrofit increase the efficiency and durability of your ventilation unit?
An old ventilation system doesn't have to be replaced straight away. Often it can't be, because there's too little space or it costs too much. But how will a retrofit help solve these problems?»

What The Tech: What is the difference between Direct current (DC) and alternating current (AC)
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?»
What The Tech: How do you keep data centers cool?
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?»
What The Tech: Securing e-mobility with green energy?
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?»
What The Tech: What to consider during installation of ventilators?
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.»

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: 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?»
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: 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? »
