SET encourages the efficiency revolution in the variable-speed drive market
In Inspirational Role Models Month, SET Sustainable Energy Technologies GmbH aims to remind the importance of constant development. Improve the performance of both, #new_business and #retrofit projects with SETCON variable-speed gearbox.
For #retrofit projects, SETCON Servos increase the total Drive train power by app. 15% without necessary Main Motor modifications. With the matching footprint with geared fluid couplings, SETCON can reuse the anchor points to make the implementation even more cost- and time-effective. The installation may be done without major foundation changes and within only 15 days on average (for further information see: SET project with swb Erzeugung AG, Germany).
SETCON variable speed gearbox would also benefit the #new_business projects with its energy efficiency up to 97% and highly competitive efficiency in a partial load. SETCON design may include an integrated lubrication oil system to supply a Main Motor and a Driven Machine inclusively. And with very small low-voltage electronics, SETCON has a very compact packaging size.
For SET as a company, the ultimate goal is to take a new, advanced, and reliable path in drive technology.
“It is important to bring inspiration to both the working team and the industry in general. At SET, we encourage R&D to continuously innovate our variable-speed technology. SETCON ensures minimal energy losses to provide the market with one of the most efficient and sustainable solutions,” comments Maximilian Hehenberger, the SET COO.
Inspirational Role Models Month is celebrated every November to remind the significance of a leading example in any community.
SETCON let your Main Motor start smoothly
SETCON Servos help the Main Motor to operate more efficiently, avoid overloads, costly equipment damage, and downtimes. Surely, it is all about SETCON Soft-Start mode. This integrated technology allows to start up the whole drive train very smoothly, with a minimum time of inrush currents.
The frequency controlled SETCON Servos gradually ramp up the whole pump string from 0% speed and acting as so-called pony motors. While starting, the Main Motor is disconnected from the high-voltage (HV) grid, until the Main Motor reaches synchronous speed, at a pump speed of app. 50%. Herby, the Main Motor´s rotor is rotating in unison with the entire drive train to build up the necessary magnetic flux. Now by connecting the accelerated Main Motor to the HV grid, the time for inrush currents is reduced significantly, in comparison to DOL (direct online) starts.
The SETCON Soft-Start mode is one of the most efficient solutions for reducing inrush current as the device enhances the voltage gradually and without stress for the system. Therefore, SETCON is cost-effective in comparison with, i.e., a Main Motor overload protection system, which may cause additional losses of overall drive train efficiency.
An inrush current is a time limited, very high current which a Main Motor faces once started from zero speed. It can have a multiple factor (up to 6 times) of rated current during starting procedure over a certain time period. Regular experiencing of high inrush current can cause motor damages, voltage dips in the supply line (which can consequently affect other equipment) and interrupt the proper Main Motor start. Furthermore, the higher level HV grid has to be designed and protected for these cases.
The Inrush current is physically inevitable, but you can choose one of the most minimizing solutions with SETCON: www.set-solutions.net/setcon

SET at the forefront of Climate Change
SET Sustainable Energy Technologies shares the recent European Commission’ s statements about tackling climate change. The need for low-CO2 production has never been greater than now.
“We saw the chaos and carnage of extreme weather… right across our Union. This is the reality of a boiling planet.” – As the European Commission President Ursula von der Leyen remarked in SOTEU speech this week, – “we shifted the climate agenda to being an economic one. This has given a clear sense of direction for investment and innovation… And we have already seen this growth strategy delivering in the short-term. Europe’s industry is showing every day that it is ready to power this transition. Proving that modernisation and decarbonisation can go hand in hand“.
Especially the energy industry is in desperate need of modernization. SET Sustainable Energy Technologies is continuously working on the leading edge of innovation in the drive technology field to contribute to a CO2-reduced energy transition and supply. Our vision is to revolutionize the market with our highly efficient and innovative SETCON variable-speed gearbox, devised based on 35 years of experience in the development of industrial drives.
Implementation of SETCON variable-speed gearbox increases the whole drive train efficiency and reduces downtime to an absolute minimum. A robust standardized gearbox design and outstanding durability of used low-voltage frequency drive technology with a MTBF of up to 60 years underlines this.
SET Sustainable Energy Technologies’ vision keeps aligned with the opinion of the EU majority, according to the recent European Commission report on climate change 2023. Three quarters (75%) of EU citizens agree that the innovative technology development is a natural step in tackling climate change. Consequently, this will make EU companies more competitive on the market.
Why SETCON is the most energy efficient VSD on market
Variable speed gearbox SETCON is valued as one of the most energy efficient drive thanks to its innovative mechanical power transmission and small, low-voltage (LV) electronic components. SETCON is an ideal solution for Driven Machines larger than 3 MW and a rated speed up to 15,000 rpm. With an energy efficiency rate up to 97% and outstanding performance in partial load, SETCON points the way ahead for a sustainable future.
Although the technology is very new and innovative, SETCON shows a good testing and performance track record of over 3 years already.
SETCON system is able to regenerate energy in partial load operation, instead of facing hydraulic losses, which in the end result in heat and corresponding cooling requirements. There are no equivalent technologies on the market with the same impressive performance by now.
SETCON allows to minimize power losses essentially. SET Servo motors feed back excess energy into the LV grid in a generator mode, and the energy will be reused by the Main Motor. Check the functionality of the SETCON gearbox: SET Interactive Animation.
Enormous amounts of energy are globally wasted, which seriously endangers our shared environment. A true energy efficiency revolution is needed, and SET works daily to make a positive contribution to this. We offer a wide range of services to our customers, including detailed calculation of economic efficiency, assessment of current situation and improvement analysis, optimization of customized SETCON concept and more.

Interesting facts about SET Planetary gear stage
Well-known that SETCON gearbox consists of a differential planetary gear. The Planet carrier with three planets is connected to two Servo motors in order to adjust a variable output speed from 20% to 105%, with an overall efficiency of more than 99%. But how is it working?
- The Planetary gear ensures the speed control at a Driven Machine (e.g., Pump or Compressor) and, additionally, regulate the torque in the entire drive train.
- The planet carrier with three planets, is connected via additional gear stages with the two Servo motors operating at variable speeds with up to 2000 rpm, located on the top of the gearbox. By turning the planet carrier in the same direction than the sun gear (connected to the Driven Machine) the speed / power is increased, and the Servos add additional power to the system. The main power flow derives from the Main Motor (connected to the Ring gear) and is superimposed by the Servo power.
- Additionally, the two Servos can “brake” the system with up to 20% of the system rated power by turning the planet carrier in the opposite direction of the sun gear. The generated energy (Servos work as generators) is fed back to the grid and is consumed by the Main Motor again. Unlike hydraulic systems, where this energy is converted into heat loss, the braking energy is used regeneratively. This results in very high system efficiencies in the partial load range. Watch Animation.
- Important advantages of Planetary gears are the up to 3 times increased torque capacity per-unit-volume (compared to spur gears). This allows a superior compactness of the device.
- These units are well-known for the exceedingly long service life. Higher stability and resistance to damage of planetary gears is kept thanks to multiple larger contact surfaces and uniform weight distribution in comparison to other gear types.
- Planetary gears are applied by humans for centuries. Under one of the theories, a similar device was used by Ancient Greeks inside the Antikythera mechanism in the 2nd-3rd centuries BC to calculate the motion of celestial bodies and dates of astronomical events. Later, in XI century Arabian engineer Ibn Khalaf al-Muradi mentioned planetary gears in his instruction on clock designs.
