Application
Dynas3 HT (High Torque)
Overview
The Dynas3 system represents a complete "loading unit". The components of the system have been optimised over many years of experience. The system has defined and standardised interfaces which significantly ease the engineering process involved getting the dynamometer to run with our specimen. The system has short delivery, installation and start-up times due to the proven concept and standard parameter records.
Features
High rated torque make these types of electrical machines optimally suitable for testing small and medium-size Diesel engines. The wide speed range also permits testing of spark-ignition engines. Speed gradients of 8,000 rpm/s and above provide the dynamic response required for sophisticated simulation tasks.
