Applications
Mounted on test benches, WB/PB 15 Series Dynamometers
allow performance and reliability testing on driving elements
such as electric motors, combustion engines, servomotors,
geared motors, reduction gears, pneumatic equipment,
hydraulic transmission systems, starter motors, electromagnetic
clutches, gas turbines and turbocompressors.
Magtrol’s M-TEST 5.0 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. Tests can be programmed to run
on their own and saved for future use allowing for valuable
time savings in production testing and incoming/outgoing
inspection.
