Electrical Machine Testing

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.

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.

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.
