Dynamometers are the main element in a test cell. They are the components exposed to the hardest working conditions. The range of performance of modern engines demands dynamometers that are of the highest quality technologically, while also highly reliable and equipped with precise measurement devices. AVL dynamometers meet these requirements in an optimal way. BENEFITS AT A GLANCE • Dynamometers are available for different applications • Test cell design results in a long life span and low maintenance �� Fast tor��ue response is provided ��y rotor��u�� vector control of the stator current • Low mass moment of inertia allows a high-speed gradient • IGBT converters with random pulse pattern reduce the electrical noise in the machine • Recuperation of energy especially in endurance tests saves costs and energy • Compact and maintenance-friendly design TASK Different test procedures and different engines require different dynamometers. Engine testing with the original vehicle exhaust system requires space where the dynamometer is normally mounted. A dynamic dynamometer is needed to run dynamic test cycles. The development of intelligent powertrain components through to hybrid systems puts a load on all components, which is comparable to the road test. Therefore, the inertia of the dynamometer should be equal to the inertia of the vehicle’s wheel. Combustion engines with high power are also calibrated and tested in low power ranges. Therefore, the requirements for torque measuring systems and their accuracy increase. Tor��ue peaks should not in��uence any technical values of the tor��ue- measuring system. Measuring units can be changed, but the dynamometer must run with low maintenance during its whole lifetime. In case of disruption, the fast delivery of spare parts and well trained engineers must be available to support the customer. It is also important that it is possible to upgrade dynamometers. / 98
