Our Range of Engine Test Beds:
All test beds serve for loading of engines, for performance testing and for
measurement and registration of other values measured at the engine and of
emissions of the engine.
Regenerative 4-Q-dynamometers are also able to drive and therefore also suitable
for testing other rotating machines beyond prime movers (like pumps, compressors
etc). In case only such machines and no prime movers should be tested, we can
offer test beds which only drive (drive dynamometers).
Fields of application are research, development, quality control and education (for education we particularly recommend our test beds type MP and MPW Modular).
Braking dynamometers
air-cooled and/or water-cooled
Advantages of air-cooling:
- low-maintenance
- suitable for tropical humid climate
- delivered ready to be put into operation
- low additional investment
MP
10 ... 500 kW
with air-cooled eddy-current brake
particularly for testing
- passenger car engines
- truck engines
- electric motors
- hydrostatic motors
- tractors at their power take-off shaft
MPW Modular
0,5 ... 40 kW
with air-cooled eddy-current brake
particularly for testing
- smaller electric motors
- smaller slowly running 1-cylinder engines
- drive units of e.g. two-wheelers
MPW F
0,5 ... 40 kW
with air-cooled eddy-current brake
for testing
- flange-mounted electric motors
HV(U)
1 kW ...
low-inertia braking dynamometer, water- or air-cooled
for testing e.g.
- high-speed internal combustion engines as chain saw engines
- low-speed internal combustion engines with one or few cylinders
EV
... 1000 kW ... ?
electric generators, loaded by resistors
particularly for testing
- passenger car engines
- truck engines
- transmission units with combustion engines
SE
... 720 kW
with water-cooled eddy-current brake
particularly for testing
- passenger car engines
- truck engines
SH
... 6700 kW
braking dynamometer with water brake
for testing
- also big internal combustion engines without time restriction
Regenerative 4-Q-Dynamometer:
E
with frequency converter
for testing
- internal combustion engines
- electric motors
MPH
e. g. 150 kW, 5000 rpm
for testing
- internal combustion engines
low moment of inertia thanks to high pressure hydrostatics, no electric interferences because there's no high performance electronics, response characteristics as required
