HBM eDrive Testing: Power Analyzer and Data Acquisition System for Testing Electrical Inverters

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. This is the reason why HBM eDrive Testing helps you to better understand the electric drive and its losses. This knowledge and understanding is important for the optimization of the drive as well as the increase of the efficiency.

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

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


The 2 components of HBM eDrive Testing:

  • Power Analyzer: Measures and calculates electrical signals and power in real-time on up to 51 channels and mechanical power with up to 6 torque / speed signals.
  • 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

  • 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
  • Formula database for adaptation to special applications such as multi-level inverters

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

One System Fits All

  • Measurement channels for electrical AND mechanical values
  • Temperature inputs - insulated up to 1 kV
  • CAN bus input
  • Simultaneous sampling of all signals and storage in a data file
  • Power analysis, performance measurement, acquisition of non-sampled raw data by operating point for the determination of the characteristic field or continuous storage for start-up tests

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

Efficiency Mapping in Minutes

  •  Dynamic, fast determination of all performance variables on all channels in real time thanks to digital cycle detection
  • Input of own real-time formulas for evaluations, e.g. Cable losses
  • Analyzes such as space vector computation and dq0 transformation in real-time
  • Fast positioning by shortest measuring times per working point
  • Metal loss, copper loss characteristic maps or MTPA curves by complex analysis of the raw data in the measuring device

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.
