Who is behind KOSTAL Drives Technology? What do we do? You will find an answer to these questions and a brief overview of our success story on this page.
MASSIVE CHANGES IN THE FIELD OF ELECTRICAL DRIVE SYSTEMS
The increasing meaning of energy costs as well as greenhouse gas emissions and the accompanying implementation of comlulsory efficiency standards lead to a perspectively conversion from inefficiently run asynchronous machines to inverter-fed synchronous machines. To achieve an efficient control of synchronous machines, however, this change requires the use of a positon sensor to determine the rotor position.
The elimination of the positon sensor used for control of synchronous machines would indeed offer advantages for almoust all applications, either concerning the reduction of cost and space, the lower failure probability, or an increase of robustness. Especially, it would be useful to dispense with this expensive and vulnerable mechanical sensor technology in case of cost sensitive and security-critical applications.
PROBLEMS OF SENSORLESS CONTROL SCHEMES
However, common sensorless control schemes lead to high development costs and risks due to their technological requirements, and show some disadvantages compared with control schemes using a position sensor. Examples include the necessary reduction of dynamic, the emission of noise at standstill, parameter dependencey, problems affecting the transition between low and high speed and the lack of suitability for machines with concentrated winding.
WE HAVE THE SOLUTION
As part of our research, we have succeeded in realizing applications with increased demands on efficiency and performance even without encoders, thereby reducing system costs and the probability of failure. Today, Kostal Drives Technology enables sensorless applications that were previously only possible with position sensors. Our technology can be found in the INVEOR product family of KOSTAL Industrie Elektrik GmbH.
Our success story
KOSTAL Drives Technology GmbH was founded in May 2019 as a result of a takeover of Bitflux GmbH by the drive technology specialist KOSTAL Industrie Elektrik GmbH, which acquired 100% of the shares. Bitflux GmbH was founded in 2016 by a team of scientists from the prestigious Chair for Electrical Drive Systems and Power Electronics of Prof. Dr.-Ing. Dr. h.c. Ralph Kennel of the Technical University Munich (TUM).
As part of the KOSTAL Group, KOSTAL Drives Technolgy thus benefits from its strong position as market leader in the field of decentralised drive technology and the expertise gained from more than 20 man-years of research and development in the field of sensorless control.
Funding phase II EXIST Transfer of Research
From April 2017 to May 2018, another research project on sensorless control of synchronous machines at Bitflux is funded by the Federal Ministry of Economics and Energy (BMWi) and the European Social Fund (ESF) as part of the programme EXIST Transfer of Research.
Funding phase I EXIST Transfer of Research
From July 2015 to March 2017, a research project on sensorless control of synchronous machines at the TUM is funded by the Federal Ministry of Economics and Energy (BMWi) and the European Social Fund (ESF) as part of the programme EXIST Transfer of Research.
