Setting New Standards in Power Transmission for EESM Drives Externally excited synchronous machines (EESMs) are emerging as a key alternative in electric mobility — especially since they eliminate the need for permanent magnets and rare earth elements. What has been missing until now is a robust, real-world solution for rotor power transmission under demanding conditions. At Schunk, we've developed exactly that: a wet-running current transmission solution that enables ✅ reliable performance even in direct contact with cooling oil ✅ consistent efficiency throughout the vehicle’s lifetime ✅ seamless integration into existing motor architectures The system builds on our proven carbon brush technology, specially adapted for the electrical and thermal requirements of next-generation automotive drives. It's already being tested in first prototype applications with OEMs. 🔍 Dive deeper into the technology in our latest blog post: https://hubs.ly/Q04p7GCc0
