“HBM eDrive Testing” ensures efficiency mapping in minutes rather than days, and thus goes far beyond conventional solutions that use power meters and subsequent PC analysis. The modular measurement system can be upgraded from 3 to up to 51 power channels per mainframe at any time. It is ideal for 3-phase applications and, with the latest enhancement, also for applications with multiple channels such as 6-phase machines, hybrid or multiple-motor drives.

Data acquisition per set point and fast efficiency mapping

In addition to its power analyzer fun HBM eDrive Testing enhanced power analyzer actions, “HBM eDrive Testing” provides all the features of a cutting-edge data acquisition system (DAQ). It allows the synchronous acquisition of electrical signals as well as torque, rotational speed, temperature, CAN bus, vibration, and many other measured quantities. All data is stored in real time, either continuously or driven by set points.

The T40B and T12HP torque transducers (for the highest standards of precision) ensure precise acquisition of mechanical quantities. High-voltage probes with up to 7.2 kV rms enable medium-voltage motors to be directly connected to the measurement system, without affecting the precision of data acquisition or the safety of the user. Unique, isolated digitizers are available for use with motors in the high-voltage range, exceeding 10 kV.

Multiple interfaces for your automation system:

  • EtherCAT real-time transmission of the power values (1000 result blocks per second)
  • Software transfer of power values (20 result blocks per second)
  • Programming interfaces for Windows (API, RPC) and Linux (RPC) for control and setting
  • Functional libraries and examples for integration into LabVIEW or DIAdem
  • Data routines for reading data with many evaluation programs such as MATLAB or LabVIEW
  • Optical Ethernet interface for remote control with safe isolation of HV area from the control area.
