Test-bench measurement technology for developing more efficient electric drives

HBM’s “eDrive measurement system” offers optimized test-bench measurement technology for increasing the efficiency of electric drives and thus enhancing energy conversion.

HBM’s solution from a single source includes Genesis HighSpeed data acquisition with integrated Perception software and HBM torque transducers to ensure reliable test results. The integrated measurement system permits synchronous, highly dynamic acquisition of both electrical and mechanical quantities and data storage in a standardized format with up to 200 MB/s. Voltage signals up to 1,000 V are recorded directly, i.e. without voltage dividers, and with sampling rates of up to 2 MS/s.

HBM torque transducers with up to 0.03 accuracy ensure highly precise acquisition of the mechanical quantities. Using an integrated measurement system means that no time-consuming and error-prone synchronization is required, since all HBM measurement components are perfectly matched to each other. Long-term tests involving two million measurements per second per channel can be run for several hours.

Unlike conventional methods, this approach allows continuous storage of raw data that enable more detailed analysis of the drive train even at a later time. All in all, the HBM measurement system offers high-quality measurement data providing decisive insights for optimizing the drive components of electric vehicles.
