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.
Power Analyzers to Test Inverter Driven Electrical Machines
The HBM eDrive series of Power Analyzers are with unparalleled power computation based on digital cycle detection. Thus, they deliver reliable results also in dynamic load changes, where conventional power meters just fail. With enough sample rate to cover all current inverter technologies, they can be expanded with more channel, higher sample rates, or other inputs to match every need you might run into in the future.
- 3 to 51 power channels per mainframe

eDrive Power Analyzers for Demanding R&D Applications and System Integration
eDrive Power Analyzers offer 3, 6 or 9 power channels with a sample rate of 2 MS/s; they can be expanded in channel count, or with mechanical inputs like acceleration or temperature, or with higher sample rate input boards. They use Perception Enterprise / eDrive software offering the usability of a POWER METER combined with the flexibility of a DAQ system. “t” mainframes are used using an external PC, while “I” system feature an integrated WIN10 PC.
