More efficiency in the development and prototyping of rotors
Establising robust and efficient balancing processes for all rotating components of an e-drive system during the development phase will help reduce noise and vibrations. Further manufacturing and operational issues can also be avoided.
Noise and vibration are a well-known cause of problems for electronics and aircraft structures. They cause discomfort, increased maintenance efforts, and fatigue damage – a high risk, especially in aviation.
Balancing starts with the design. Therefore, it is recommended to involve the experts from Schenck during the development of electric drives for aircraft and eVTOLs in order to design rotors that can be sucessfully balanced. This way, the required balancing strategy can be considered from the beginning.
At the design stage, it can be estimated from geometric tolerance data what unbalances can be expected from the production process. Once the first prototypes are manufactured, Schenck can run them to operating speed and if necessary, to overspeed. For example, this allows settling effects due to the weight-optimized design to be measured, without the respective service drive (e.g. the stators and controls) having to be available. Alternatively, spin or burst tests can also be carried out. Schenck has the appropriate equipment and know-how for manufacturing tooling to accomodate rotors in the balancing or spin processes.
In its new Green Technology Center, Schenck, as the world leader in balancing technology, has consolidated all its services related to the development and production of E-Propulsion rotors.
We would like to inform you that we will be participating in this year's electric & hybrid aerospace technology symposium in Frankfurt am Main, which will take place on October 30th and 31st. We look forward to the opportunity to engage with you and would be pleased to have you visit.
