      1. HBM eDrive Testing: Power Analyzer and Data Acquisition System for Testing Electrical Drives

        HBM eDrive Testing is the revolutionary system for testing electrical inverters and electrical machines. Mechanical signals (e.g., torque) and electrical signals (current, voltage) are acquired simultaneously, helping you to better understand the electric drive and its losses in minutes rather than days. This is important for the optimization of the drive as well as the increase in efficiency.

        In contrast to conventional power analyzers, HBM eDrive Testing offers unique data acquisition and analysis capabilities in addition to power measurement.

        The modular testing system is suitable for any test in electrification for 3-phase as well as multi-channel applications (e.g., 6-phase machines, hybrid or multi-motor drives).


        The two components of HBM eDrive Testing:

        • Power Analyzer: Measures and calculates electrical signals and power in real-time on up to 51 channels, as well as mechanical power with up to 6 torque / speed signals and a typical power accuracy of 0.02%.
        • Measurement data acquisition system (DAQ): Synchronous detection of electrical signals, torque, speed, temperature, CAN bus, vibration and other measured variables. Continuous or point-controlled storage of all data in real time.

        Easy to Expand Beyond 3 Phases

        • Modular expandable to 51 power channels for multi-phase systems or multi-motor applications
        • Can be upgraded to up to 6 torque / speed inputs for up to 6 mechanical outputs
        • User formulas for adaptation to special applications such as multi-level inverters

        Grows with your requirements:
        a power analyzer for 6-phase machines or hybrid drives

        One System for All Tasks

        • Designed for motor testing or electrification
        • Measurement channels for electrical and mechanical values
        • Temperature and CAN bus inputs
        • Simultaneous sampling of all signals and storage in a data file
        • Power analysis, acquisition of raw data per set point or continuous storage for start-up tests

        Easy measurement setup:
        an integrated system instead of combining a variety of different devices

        Efficiency Mapping in Minutes

        • Input of real-time formulas for special evaluations, e.g. cable losses
        • Real-time analysis such as space vector and dq0 transformation
        • Fast mapping by shortest measuring times per set point
        • Iron loss, copper loss maps or MTPA curves

        Efficiency maps in minutes: 
        Save several hours of time by completing your analysis right at the test stand

        How to Interface with Genesis HighSpeed and/or Perception

        Would you like to integrate the HBM eDrive solution into your test stand automation? Perception software and/or the Genesis HighSpeed hardware can be used in your specific environment, in exactly the way you want.

        Several large system integrators already did integrate eDrive, using one or more of the interfaces available:

        • EtherCAT or CAN FD for hardware-based data transfer with up to 1000 result blocks/s in real time
        • API interfaces to directly control the hardware as well as the Perception software from common automation software packages
        • Data reader dll to read the data into any 3rd party analysis software like MATLAB or LabVIEW.
        • So, integration is a breeze, using the powerful tools available.
