● HBM offers eDrive testing for 6-phase machines

HBM Test and Measurement (HBM) complements its ‘HBM eDrive Testing’ enhanced power analyser with additional functions for testing 6-phase machines. This integrated solution enables torque, electrical quantities, temperatures, CAN bus, and other signals to be measured in an extended range of applications.

‘HBM eDrive Testing’ is a custom measurement system for testing inverter-fed electrical machines. Unlike conventional power analysers, HBM eDrive Testing provides unique and greatly accelerated data acquisition and analysis options.

Founded in Germany in 1950, Hottinger Baldwin Messtechnik GmbH (HBM Test and Measurement) is the technology and market leader in the field of test and measurement. HBM’s product range comprises solutions for the entire measurement chain, from virtual to physical testing. The company has production facilities in Germany, USA, China, and Portugal and is represented in over 80 countries worldwide.

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 multiplemotor drives. In addition to its power analyser functions, ‘HBM eDrive Testing’ provides all the features of a cuttingedge 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 are 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.
