Eddy Current Dynamometers are

manufactured in Two Types
Water Cooled Eddy Current Dynamometer
& Self / Forced Air Cooled Eddy Current
Retarder.
 Eddy Current dynamometers: Water
Cooled - in wide Torque rating range from
tiny 1 Nm to massive 5000 Nm. In self
cooled & Water / coolant cooled version
depends on Power rating, Speeds upto
30000 RPM.
Eddy current dynamometer, A simple dynam-
ic load system for accurate testing of all type
of Electric Motors, Air Motors, Hydraulic Mo-
tors, Engines and other rotating machineries.
It provides the ideal solution for accurate
analysis of Power, Torque, Speed, Fuel and
Lubrication consumption and quick pass / fail
testing of all type of Electric Motors, Engines,
Gears and other Rotating Machineries.
Eddy current dynamometer absorbs power &
measures Torque and Speed characteristics
with a unique braking system, which provides
frictionless Torque loading (0% to 100%) con-
stant / variable torque load, independent of
shaft speed. Torque is transmitted by a mag-
netic field with out friction or wear. It elimi-
nates mechanical loading to the prime mover,
providing longer life. In Eddy Current Dyna-
mometers torque increases as the speed in-
creases, reaching peak torque at rated speed. Low Speed High Torque PMAC Gearless Motor
EC dynamometers have low inertia as a result Test Setup
of small rotor diameter and a low residual tor-
que of approx 1%.
Cooling is provided by a water circulation
system, which passes inside the stator to dis-
sipate heat generated by the braking power.
The water cooling in the EC Dynamometer
provides high continuous power ratings & as
typical accuracy ratings of ±0.2% full scale,
depending on size and system configuration,
Mounting orien-tation of Eddy Current Dyna-
mometers is in any direction, Horizontal, Ver-
tical or inclined.
Eddy Current Dynamometer is Bi-directional,
Dry-gap Type. Being Dry operation, the only
resistance to movement of the rotor is bear-
ing friction and the minimal windage effect.
With zero excitation, an almost no-load condi-
tion is achieved over the entire speed range
