Intelligent Motion ical modelling is making it easier to eliminate sensors from motors and drive systems This is something that the TU Vienna has been working on for the last 30 years and which has been used in product applications since 2010 Depending on the needs of the application the result doesn’t only have the advantage of eliminating sensors such as expensive tachometers or position encoders it can also remove the need for test pulses The outcome is motors that can be much quieter as well as being more compact and without having to solve for EMC in sensor cables Without mechanically complicated instruments robust control of sensorless motors has also been achieved even in highly dynamic processes Perspectives in E-Mobility Many of the other trends in E-Mobility are driven by changes in storage technologies such as the shift from lithiumbased to natriumbased technologies Natriumbased batteries have the benefit of a cheaper more widely available material though development is still at an early stage and power densities are low There are also ceramicbased solid state batteries which are inflammable and thus can withstand higher currents for much faster charging However batteries remain the most expensive components in electric vehicles This makes the efficiency of the motors and inverters even more important Every reduction in energy consumption reduces the battery size needed keeping the cost of the whole system under control This is what makes SiC and GaN inverters so interesting for EV applications Another motivation in E-Mobility is to reduce sizes to minimise the compromises to overall vehicle packaging One impact of such compactness is cooling difficulties pointing the way to the greater use of liquid coolants Though this increases complexity it also creates the opportunity for better control of the excess motor and inverter heat for example to warm the battery in colder climates or conditions The challenges for intelligent motion especially in combination with new power electronics devices materials and production processes continue to throw up interesting opportunities O Univ Prof Dipl -Ing Dr techn Manfred Schrödl is chairing the session on “Advanced Control Techniques on Electrical Drives II” on 11 June 2024 2 30 p m on stage Athen and the poster presentations on “Advanced Converter Topologies” 13 June 2024 11 15 a m Hall 10 1 RESEARCH PORTFOLIO design simulation process development sampleproduction testing validation technology workshops SEE US AT Hall 6 106 11 -13 06 24 EDUCATION RESEARCH PROTOTYPES TALENTS CONTACT Prof Dr Ronald Eisele | ronald eisele@fhkiel de Prof Dr -Ing Aylin Bicakci | aylin bicakci@fhkiel de TALENT TRANSFER Exciting education trained on real challenges ADVERTISEMENT
