Flexible Mounted Engine
In this system configuration, the engine is elastically mounted on a substructure of steel or concrete, while the generator is rigidly mounted. The elastic mounts have to be specially designed for each application. The natural vibration frequency of the system's engine/elastic mount must lie sufficiently below the operating speed of the engine. With optimally designed mounts, an insulation level of up to more than 90% can be achieved. In this special configuration with an elastically mounted engine, VULKARDAN E, RATO S or RATO R couplings can be used depending on the particular requirements of the installation.
