Sumitomo Drive Technologies is expanding its range of precision gear products and upgrading its ECY series with higher torque and a plug & play drive for motor connection. The ECY series comprises high-precision shaft gears, used for example for surface machining in dental technology or in collaborative robots (cobots). Thanks to their internal cylindrical roller bearings, the gear units provide both high rigidity and higher performance in a smaller design envelope.

More energy efficiency, higher performance and better controllability are the main reasons why more electric drive systems are being operated with frequency converters. However, these devices can cause high-frequency, asymmetrical interference currents, which, as a current passage through the output and fan-side bearings, can cause damage and premature failure.

Current-compensated CoolBlue toroidal cores made of Magnetec’s nanocrystalline material Nanoperm have proven to be effective protection against such conducted interference and its consequences. In addition, the Nanoperm Line Absorbers NaLA can also be used to significantly suppress symmetrical interference currents.

Voith announces another important development – the Future Inverter Platform (FIP) – for the VEDS drive system. The new inverter has been specifically designed to meet the requirements in the commercial vehicle segment and will be integrated into future generations of the VEDS, Voith's innovative electric drive concept for commercial vehicles that has proven highly effective in numerous applications in the bus segment since its introduction in 2021. The FIP technology will go into series production without integrated DMU in 2024 and with integrated DMU in 2025.
