The modular testbed concept allows for testbed design in different performance and speed classes and additionally offers the option of functional testbed expansion – by adding software or instrumentation systems; it is even possible to add a climatic chamber module later. This makes the AVL test system a secure investment for the future. APPLICATIONS The AVL E-Motor testbeds are used for analyzing and determining electrical, mechanical, thermal and acoustic properties. Functionality, reliability and durability tests and cold start performance measurements can be implemented under realistic conditions. The integrated AVL PUMA Open™ automation system allows for fully automatic runs, so time and cost-efficient test ones for aII relevant test procedures. All measurement data is saved with a uniform time stamp and can be processed further with the data postprocessing tool, AVL CONCERTO™. The optional integration of the “Virtual Proving Ground” technology-based on AVL InMotion™ also offers a virtual development and test environment to implement integration, optimization and validation tasks even on the testbed. The test specimen is (by means of simple parameterization) integrated in a virtual vehicle environment and tested systematically with reproducible, realistic driving maneuvers. Control units within the vehicle can be emulated in AVL InMotion™ or connected as real devices to AVL InMotion™. AVL E-Motor testbed with climatic chamber module TESTBED CONFIGURATION AVL E-Motor testbeds are available as a standardized system or as a tailored testbed solution. A special adapter system used initially to set up test specimens allows for quick and simple coupling of test specimens to the dynamometer. Shaft connections are available for both low- and high-speed applications. Special integrated instruments with extremely high levels of accuracy are used to measure torque and/or efficiency. AVL offers four-quadrant-dynamometers in a variety of performance and speed classes for the entire operating range of the specimen, from zero speed up to positive/negative maximum speed. AVL’s high quality dynamometers are also characterized by very low torque cyclic irregularities resulting in the delivery of measurement results with high levels of accuracy.
