- sensorless control for reluctance and permanent magnet synchronous motors- drives of highest energy efficiency without mechanical sensors, such as motion or position sensors - full torque even at standstill- highly dynamic speed and torque control- no loss of synchronism, no permanent angular errors, not even in case of overload or low speed- no special rotor position sensor needed - thus reduction of the installation space and elimination of the sensor wires and the plug connectors- suitable also for existing safety-critical devices as a quasi-redundant position and speed control- designed as a reluctance motor: no rare earth metals needed, first highly efficient and cost-effective replacement for asynchronous machines, no magnetic field in a state without current, which is advantageous for certain functions, e.g. magnetic bearingDegree of innovation:- first highly efficient and synchronous drives at low system costs- tested and tried control method INFORM®, with many thousands of units in use - for example in medical and aviation devicesTarget groups and fields of application:- Production machines- Automotive industry - Aerospace industry- Construction machinery or heavy equipment - Ventilation and air conditioning- Medical devices- For power ranges of a few watts to megawatts - Highest energy efficiency and reliability - even in harsh environments
Today, a great deal of energy is lost in the form of heat, such as unused heat from industrial plants or vehicle exhausts, which is simply emitted into the environment. Being able to store this heat would be a tremendous step forward. This stored heat could, for example, be used when starting engines that cause very high emissions when started from cold.
At TU Wien, an innovative solution has now been developed for this problem, which involved the collaboration of three institutes: Chemical Engineering, ...
Sunshine and wind are not aligned with the needs of the electricity industry. In order to keep the electricity grids stable, despite an increasing proportion of alternative energy sources, storage technologies that make economic sense are required. Pump storage power stations are ideally suited for this. However, they previously only made economic sense on a large scale. The need to stabilise subordinate local electricity grids with smaller storage power stations is now increasing. In this way, expensive p...
The basic idea comes from inside the earth: at extreme temperatures and under great pressure, materials can be formed there that would have great difficulty forming on the surface of the earth. For the chemist Dr Miriam Unterlass from TU Wien’s Institute of Materials Chemistry, this was what prompted her to think about new methods of synthesis for industry. And she did, in fact, manage to manufacture crystals made from special high-performance materials under heat and pressure, which can now be used to sig...
It started off with a really simple idea: can you improve electric machines by combining several rotors into an efficient single system? Professor Manfred Schrödl showed that this is actually possible and combined four generators with a special gear to form an innovative ‘planet generator’. A high-performance prototype of the compact planet generator will be presented for the first time at the 2018 Hanover Fair. The machine is a generator, motor and gear unit at the same time and it is extremely compact, w...
3D printing is set to become one of the major technologies of the future, but all previously available 3D printing technologies come with certain disadvantages. Some printing processes result in unclean, rough surfaces; with others, the material properties of the products leave something to be desired.
The start-up company Cubicure specialises in manufacturing optimised resins that resolve these problems. The ‘hot lithography’ technique developed by Cubicure brings together the advantages of processes us...
