With our NVH test systems for validating e-motors, we support all unit under test (UUT) variants. Our aim is to create development environments that can solve NVH development challenges quickly, efficiently, and sustainably. NVH test systems offer a range of solutions depending on the priorities of the main features, which can be summarized in three main areas across all UUTs:
• Premium setup
• Precision setup
• Efficiency setup

The focus of this test system type is on developing ultra- |
Precision | This setup focuses on the on the exact alignment of micro- phones in the testbedas described in the ISO3745.The design allows for a complete microphone hemisphere without inter- ference surfaces of the mechanical setup. |
Efficiency | Efficiency is a major topic in the transformation of existing testbeds. For customers who have invested in an NVH chamber and/or a component testbed, we have created our efficiency product line. The focus is on conveniently trans- forming the testbed into a solution that seeks the best com- promise between reasonable power and NVH performance. |
Premium Setup
- Highest level of measurement accuracy and wide homogeneous free-field condition thanks to optimized
test system design - Ultra-low noise level from test system to enable out-
standing SNR (signal-to-noise ratio) for guaranteed
class 1 measurement results - Fully independent vibration behavior of UUT thanks to innovative decoupling concept
- Full performance in power, torque, and speed, combined with seamless integration into the AVL toolchain
Precision Setup
- Uncompromised compliance with ISO3745 regarding microphone setup
- Precise detection of single-spot noise phenomena for the UUT thanks to availability of full microphone array
- Fully independent vibration behavior of UUT thanks to decoupling concept
- Full performance in power, torque, and speed, combined with seamless integration into the AVL toolchain
Efficiency Setup
- Easy and fast upgrade of existing anechoic chambers (e.g. engine or propulsion system testbed) to high-performance e-motor NVH test systems
- Minimized acoustic reflections due to optimized shape and surface of dyno enclosure
- Flexibility to use the NVH test chamber for different UUTs (e-motor, e-axle, powertrain) due to easy and free positioning of the test system inside
- Full performance in power, torque, and speed, combined with seamless integration into the AVL toolchain
