With the exception of the inline torque meter, the majority of the parts are the same as those used in the wellknown AVL DynoExact APA dynamometer. The high permissible load on the shaft end allows users to mount an inline torque meter and an elastic coupling to reduce torque oscillations. PRINCIPLE The dynamometer is controlled by an IGBT converter. The recovered energy is fed back to the grid with a power factor of one. The random IGBT pulse pattern reduces the harmonics on the mains and the acoustic noise at the machine. A highly dynamic torque capability is provided by the vector control of the AC machine. The low mass inertia makes it possible to conduct transient and dynamic test runs. Extremely robust asynchronous foot-mounted machine for speed- and torque-controlled operation. State-of-the-art IGBT technology with pre-selectable switching frequencies produces almost sinusoidal currents to the electrical motor and to the mains supply. BENEFITS AT A GLANCE • Best AC motor efficiency with lowest mains distortion due to latest state-of-the-art IGBT technology • Highest torque response by rotorflux-vector-control of the stator current • High speed gradient due to optimized inertia • Robust design for operation under extreme ambient and environmental conditions • Easy installation and commissioning APPLICATIONS The AVL DynoRoad series is designed for steady-state and dynamic test runs. They can be used for various applications such as vehicle simulation and exhaust emission measuring of passenger car and truck engines. They can also be used for other types of applications such as component testing and friction tests.
