Magtrol’s Model DSP7000 High Speed Programmable
Dynamometer Controller employs state-of-the-art Digital
Signal Processing Technology to provide superior motor testing
capabilities. Designed for use with any Magtrol Hysteresis,
Eddy-Current or Powder Dynamometer, Magtrol In-Line
Torque Transducer or auxiliary instrumentation, the DSP7000
can provide complete PC control via the USB or optional
IEEE-488 or RS-232 interface. With up to 500 readings per
second, the DSP7000 is ideally suited for both the test lab and
the production line.

In the laboratory, the DSP7000’s high sample rate provides
superior resolution for data acquisition and curve plotting.
This allows for capturing more usable motor test data during
switching, breakdown and other transitional areas of the
motor test curve. For production and incoming inspection,
the DSP7000 displays torque, speed and power at all times,
allowing the Controller to be used as a manual stand alone
unit or as part of a complete PC system.

Magtrol’s M-TEST 7 Software (
sold separately
) is a state-
of-the-art motor testing program for Windows®-based data
acquisition. Used with the Magtrol DSP7000 Controller,
Magtrol M-TEST 7 Software provides the control of any
Magtrol Dynamometer and runs test sequences in a manner
best suited to the overall accuracy and efficiency of the Magtrol
Motor Test System. The data that is generated by Magtrol’s
Motor Testing Software can be stored, displayed and printed
in tabular or graphic formats, and can be easily imported into
a spreadsheet.
Written in LabVIEW™, M-TEST 7 has the flexibility to test
a majority of motor types in a variety of ways. Because of
LabVIEW’s versatility, obtaining data from other sources (e.g.
thermocouples), controlling motor power and providing audio/
visual indicators is relatively easy.
Magtrol’s M-TEST 7 Software is ideal for simulating loads,
cycling the unit under test and motor ramping. Because it is
easy to gather data and duplicate tests, the software is ideal
for use in engineering labs, production testing and incoming/
outgoing inspection.
