Electrical Machine Testing & Powertrain Testing

Gain the competitive edge in electrification with HBM Power Analyzers. Designed specifically for the testing of electrical machines and inverters, HBM systems offer significant benefits over conventional power analysers when it comes to electrical machine and powertrain testing.

Premium electrical machine testing from HBM comes in the form of the eDrive solution, which covers the entire measurement chain: high-precision sensors, powerful instruments, and intuitive software. Mechanical signals (e.g. torque) and electrical signals (current and voltage) are acquired simultaneously, helping engineers to better understand the electrical drive and its losses faster and more accurately than ever before.

 

Two critical selling points of the eDrive electrical machine testing solution include:

  • High accuracy 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 Base Power Accuracy of 0.02%. 
  • High performance Data Acquisition System (DAQ): Synchronous and continuous recording of electrical signals, torque, speed, temperature, acceleration, CAN bus and much more. Real time or post process analysis for result verification, mappings or advanced analysis like electrical and NVH correlations.

Easy to Expand Beyond 3 Phases

  • Expand to 51 power channels for multi-phase systems or multi-motor powertrain testing applications
  • Upgrade to up to 6 torque / speed inputs for up to 6 mechanical power channels
  • Adapt custom user formulas for special applications such as multi-level inverters

Efficiency Mapping in Minutes

  • Real-time formulae input for special evaluations, e.g. cable losses
  • Fast mapping by shortest measuring times per set point
  • Real-time analysis such as space vector and dq0 transformation
  • Raw data storage enables advanced analyses such as iron loss, copper loss maps, or MTPA curves

Infographic – Electrical machine and powertrain testing

The eDrive solution from HBM covers the entire measurement chain: high-precision sensors, powerful instruments and  intuitive software. Mechanical signals (e.g. torque) and electrical signals (current and voltage) are acquired simultaneously  and help engineers to better understand the electrical drive and its losses faster and more accurately than ever before.

Test engineers performing high-speed power measurements of inverter-driven electric machines can now combine CAN bus control signals with data about electrical (current, voltage) and mechanical (speed, torque) signals. The simultaneous storage of all types of data by a single Power Analyzer enables faster and more flexible set-up of test benches.

CAN – a simple and effective way to manage complex Tests

CAN bus support means you can acquire or transfer data via CAN or CAN FD formats, as required; or manage experiments via CAN bus control commands.

CALIBRATE

Compare and correlate the measured values of the machine with what the machine’s controller is estimating, by bringing external sensor signals into the Power Analyzer. Save all signals to a single file for review, post-processing and auditability.

  • Records up to 1.000 input signals via CAN / 500 via CAN FD
  • up to 4 input ports from the CAN bus into the GEN DAQ mainframe
  • includes stand-alone recording and local storage

TRANSFER

Provide feedback for the automation system by transferring calculated results of machine measurements into a different data system (e.g. the dynamometer).

  • Transfer via CAN or CAN FD
  • up to 1000 result blocks/sec
  • includes up to 240 asynchronous results per block

CONTROL

A familiar interface which provides simple and easy-to-use controls for data acquisition.

  • Receive remote control commands from the CAN bus (e.g. START or TRIGGER)
  • transfer status information to the CAN bus (e.g. IDLE or RECORD)

Faster, More Flexible Set-up of Test Benches

Extending the scope of eDrive Power Analyzers to include CAN bus data gives Test Engineers three major advantages:

  1. speed of data handling, and the ability to identify any variations between the target values sent from the ECU via the CAN bus to the inverter and the actual values captured by direct measurement.
  2. flexibility for data acquisition, adding signals from the CAN bus and ease of handling test results
  3. simplicity when building test stands, as data transfer and control is done via one common bus

The CAN bus interface is available as an option for new hardware and as an upgrade for most HBK Power Analyzers already in the field.

How to Interface with Genesis HighSpeed and/or Perception

Would you like to integrate the HBM eDrive electrical machine testing 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
  • The nCode GlyphWorks software for post-acquisition signal processing and power calculation
  • 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.
