HBM Launches an Integrated eDrive Test System for Electric Motor and Inverter Analysis
|By Business Wire

HBM, Inc. (www.hbm.com),
a leading manufacturer of data acquisition systems, analysis and
calibration software, strain gauges, and transducers and sensors, has
introduced a new solution for eDrive testing, a powerful, integrated
system for measuring the performance and efficiency of electric motors
Making the measurements necessary to increase the efficiency of an
electric drive train used to be a real chore. Typically, a power
analyzer is used to make these measurements, but while these instruments
do provide calculated results, they do not provide the raw data that
engineers actually need.
“HBM’s new eDrive package is the only completely integrated test
solution on the market that allows engineers to record, verify and study
both electrical and mechanical parameters under dynamic conditions,”
said Mike Hoyer, HBM applications engineer.
The eDrive testing solution combines HBM’s T12 or T40 torque sensor, the
most accurate torque transducers in each respective class; the GEN3i
data acquisition system; and as an option the Quantum 1609B temperature
satellite to provide synchronous, dynamic, and continuous acquisition of
mechanical and electrical signals from an electric drive system. In
addition to making temperature, torque and rotational measurements, the
eDrive testing solution can make measurements from as many as 18 current
and voltage channels at voltages up to 1,000 V, at a sampling rate of up
to 2 MS/s.
The system incorporates an intuitive eDrive software GUI developed
exclusively for electric motor and inverter testing. For noise immunity,
optional high voltage 2-wire shielded cables with safety banana
connectors are provided in various lengths ensuring improved signal
integrity. For additional safety from high voltages and currents, an
optical Ethernet interface offers complete display and control from a
remote location or control room via an external PC.
The mechanical torque and rotational signals are recorded by the use of
a rotating torque sensor with an integral slotted disc for speed sensing.
The system not only provides the raw data, but real-time analysis as
well. Included with the system is powerful software that provides a
complete characterization of an electrical drive train. The software
analyzes the raw data and displays real time results, such as true,
reactive and apparent power and efficiency calculations. It also allows
for more extensive verification and analysis of the corresponding raw
data. A freely programmable formula database can be used to determine
equivalent circuit diagrams, calculate air gap or cogging torques for
motor analysis plus calculation for space vector, part transformation
and THD to analyze inverter behavior.

The cloud era has reached the stage where it is no longer a question of whether a company should migrate, but when. Enterprises have embraced the outsourcing of where their various applications are stored and who manages them, saving significant investment along the way. Plus, the cloud has become a defining competitive edge. Companies that fail to successfully adapt risk failure.
The media, of course, continues to extol the virtues of the cloud, including how easy it is to get there. Migrating...
