General
information
Presenting a family of
powder, eddy current and
hydraulic dynamometers.
Braking dynamometers are measuring class, electro-mechanical devices. They are
used for artificial load simulation on a variety of prime movers and passive elements.
Go Power Systems’ range of dynamometers serve the testing needs of driving and driven
elements for performance verification or design validation of electric motors, IC engines,
fans, blowers, gear-motor combinations, servo motors, starter motors, clutches and
transmissions. Three different forms of dynamometers are presented for optimal selection
based on the test points and torque-power absorbing requirements.
Go Power System’s have intelligent control units that provide cme excitation to eddy
current and powder dynamometers. The controller uses an infinitely adjustable load setting
input either by potentiometer or external load reference signal. An internal DSP based
controller performs closed-loop torque control of the associated dynamometer and
annunciates limit values. Computer connectivity through a communications port enables
remote control and sequencing of cyclic tests with user-definable, load-time profiles. The
generated data can then be captured, displayed and retrieved in graphic or tabular formats.
For the hydraulic dynamometers, there are three options available from the simple manual
control of the VS-3XXX valves to the full GPS 6000 Data Acquisition System which
provides closed loop water valve control.
There are 4 combinations:
1. VS manual valve
2. TMS-OIL in remote manual
3. TMS w/EPS-6000
4. TMS w/V4 controller
5. F series valves w/EPS-6*

Dynamometer selection
Choosing the right type of dynamometer requires a balance between its absorption
characteristics and those of the prime mover. Go Power Systems understands the loading
limits, speed range and power capabilities.

The following guidelines will help to determine which dynamometer series and model most
suitable for your application.
1. Know the speed-torque characteristics of the engine under test.
It is important that power is simply a calculation that reflects the relationship
between torque and speed throughout the operating range of the engine.
When determining what dynamometer will support your test criteria, you need
to know the peak torque and the speed at which peak torque is developed for
each engine you’ll be testing. This data can usually be obtained through the
engine manufacturer.
2. Know your test points.
3. Choose the dynamometer model.
Plot out your profile test points on a power torque vs. speed duty graph, also
known as a “Duty Curve”. Each series and model dynamometer has a different
absorption characteristic and therefore a different duty curve associated with
its abilities.
Once those parameters are determined, overlay a test profile on the Go Power Systems
dynamometer duty curve. These points should contain a dynamometer curve with
the power and torque to hold or achieve and at the speed ranges.
Typical dynamometer duty curve
Refer to a typical duty curve and nomenclature below, example shows a model
DT-1000SG hydraulic dynamometer duty curve.

DP- Powder dynamometer
operating principles
Magnetic Particle brakes and dynamometers are well suited for applications demanding
medium torque from zero to medium speed ranges. Unlike Eddy current forms of
dynamometers, which develop torque, on electro-dynamic principles, magnetic particle
devices, develop torque on electro-mechanical principles. This gives it an important
advantage that torque developed is practically independent of speed.
The powder dynamometer uses a fine, free-flowing, stainless steel, magnetic powder that
forms the medium for torque transmission between driving and stationery members of
powder dynamometers.
The unit is energized by an electromagnetic field, generated by a stationary coil that
surrounds its active members. When excited by a low DC voltage (24 V d.c, @ 2.5 A level)
the magnetic field, tends to compact the magnetic powder in the interspaces, in proportion
to the field current. This causes a proportionate increase in the torque developed. When
the field coil is de-energised, the magnetic field collapses and the powder flows back to
internal powder pockets.

DA/DE- Eddy current dynamometer
Eddy current dynamometers operate on the principle of slip losses that occur when an
electrically conductive drum rotates against a stationery and non-uniform magnetic flux
distribution, formed around its periphery. The relative speed between the stationery flux
and the rotating drum causes flow of eddy currents, in the drum material.
The reactive magnetic field, resulting from induced currents, is responsible for the braking
torque developed by the unit.
What is the difference between DA and DE eddy current dynamometers?
DA dynamometer uses air cooling DE dynamometer uses water cooling.
Power dissipation figures refer to peak torque at base speed.
Selection is based on max torque demanded at minimum operating speed.

speed or constant torque over mid- to- high speed ranges.

Water is both absorption cooling media.
Low maintenance – occasional re-lubrication.
No consumables.
Dynamometers have built-in torque and speed sensors.
Facility for site calibration using calibrated weights.
Load control is performed on inlet.
Outlet has fixed sized orifice sized to maintain each models duty curve.
D/DT SG hydraulic dynamometer
The hydraulic engine dynamometer is a turbulent-action water brake and operates on a
water control principle. This system applies torque to oppose the rotation of the engine.
As the amount of water within the dynamometer is increased, the load, or resistance on the
engine also increases. The resistance developed by the dynamometer increases with the
speed of the engine. *The dynamometer can be operated continuously at any power level
within the limits of its duty curve.
Go Power Systems offers 2 series of hydraulic (water brake) dynamometers:
D-57SG Series high speed -medium torque the DT-X000SG Series low
speed-high torque
*The dynamometer may be operated continuously within the duty curve, however hydraulic
machines are regularly used for short term performance testing at considerably higher power
values, (torque levels remain with the maximum published level). This does result in rapid heating
of the water within the machine which may result in localized vapourization. Go Power systems
accepts no responsibility for any resulting loss due to operation outside the publish performance
characteristics of the individual dynamometer.

Go Power Systems Brake Controller is a self-contained unit, suitable for either table-top or rack
mounting and employs high speed digital signal processor based technology for control of
Go Power Systems dynamometers such as eddy current and powder dynamometers etc.
The internal digital signal processor, performs closed loop speed torque control of the
associated dynamometer, and annunciates limit values, that are set on its keypad. The keypad
also serves to configure user-definable analogue input signals. A 32 character, backlit LED
display of torque, speed and power, can be scrolled through using the keypad. Computer
connectivity through RS232 port enables remote control and sequencing of cyclic tests
with user-definable load-time profiles. The data generated can be captured, displayed and
retrieved in graphic or tabular formats with an optionally available software package.

Designed for use with the TDA-1,2,3000. Attaches
directly to flywheel through crankshaft bolts. The
50015 coupling adapter then bolts to the mounted
50156-XX flywheel adapter, followed by attachment
of the 50112 flex coupling to the assembly. The
dynamometer is then mounted to the engine flywheel
housing while the mainshaft engages the splined
drive of the 50112, thereby linking the dynamometer
to the flywheel.

The CT-102/3 cooling tower is a single pass type heat exchanger used primarily in
automotive, small diesel, and other engine applications with low cooling water volume
requirements. This unit operates on a through-flow principle.
Operation Overview:
Hose connections are made from the CT-102/3 to the engine. The drain valve is then shut
and the fill valve opened. When the level in the tank indicates full in the sight glass, the fill
valve is shut and the engine is started and warmed up. Once normal operating temperature
is reached, the temperature regulating valve will open allowing cold, fresh water in thereby
displacing cycled water through the overflow tube until desired temperature of the system
is reached. This process is continuous under steady-state operating conditions.
