HBM Test and Measurement products are available through Durham Instruments – like the eDrive power analyzer, a revolutionary solution for testing electrical drives, inverters, and machines, as well as power trains. This device acquires mechanical data and electrical signals at the same time, so users can better understand an electric drive and its losses in mere minutes: a major advantage for the optimization of the drive and for the boost in efficiency.
One system for all tasks
This versatile unit works for many important applications, especially motor testing or electrification; it also suits measurement channels for electrical and mechanical values, simultaneous sampling of all signals and storage in a data file, and power analysis, with acquisition of raw data per set point or continuous storage for startup tests. It functions with accelerometer, temperature, and CAN inputs. Durham Instruments recommends it for use in general manufacturing, aerospace, automation, the medical field, the military, power generation, alternative energy, transportation, and research and development.
The eDrive provides unique data-acquisition and -analysis capabilities in addition to power measurement, unlike standard power analyzers. It offers easy measurement setup, as an integrated system rather than a combination of various devices. HBM modular power analyzers are useful for any electrification test for three-phase and multi-channel applications, such as six-phase machines and hybrid or multi-motor drives.
This instrument has two primary aspects: a high-accuracy power analyzer and high-performance data-acquisition system. The former measures and calculates electrical signals and power in real time on up to 51 channels, plus mechanical power with up to six torque/speed signals and a typical base power accuracy of 0.02 per cent. The latter provides synchronous, continuous recording of electrical signals, torque, speed, temperature, acceleration, and CANbus – plus real-time or post-process analysis for result verification, mappings, or advanced analysis like NVH and electrical correlations.
The eDrive is easy to expand beyond three phases, with user formulas for adaptation to special tasks like multi-level inverters. Check out this video for a closer look:
