Model HD-500 Hysteresis Dynamometer
The Hysteresis Braking
System All
Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis
Braking System which provides frictionless torque loading independent
of shaft speed. The Hysteresis Brake provides torque by the
use of two basic components - a reticulated pole structure and
a specialty steel rotor/shaft assembly - fitted together but
not in physical contact. Until the pole structure is energized,
the drag cup can spin freely on its shaft bearings. When a magnetizing
force from the field coil is applied to the pole structure,
the air gap becomes a flux field and the rotor is magnetically
restrained, providing a braking action between the pole structure
and rotor. Other Types of Hysteresis

NEWMicro Dyne
Magtrol's new Micro Dyne is the FIRST and ONLY system designed specifically for testing miniature/micro, low-torque motors.
Engine Dynamometer
Used for testing internal combustion engines up to 10 horsepower
(7.5 kW).
Dial
Weight Dynamometer

motor testing.
Special Dynamometer
Designs and Modifications
Low
Speed
Testing
For low speed motors, such
as gear motors with maximum speeds of less than 200 rpm,
Magtrol offers additional encoder options that allow for
increased resolution of the speed signal. Please refer
to the data sheet
for ordering information.
High
Speed
Testing
For certain models, Magtrol
can provide a dynamometer which can operate at higher
than rated speeds.
Mechanical
Modifications
Magtrol can provide customized
base plates, riser blocks and shaft modifications.
Analog
Output
Magtrol can provide a 0-5
VDC analog output for the torque signal and a TTL speed
signal from the dynamometer.
