DC Dynamometer For Motor Testing.
These dynamometers are suitable for testing of
rotating machines AC or DC, basically these are also used as indirect
method of loading of any machine. The construction features are
basically a DC Shunt Generator constructed in such a way that it is able
to indicate the torque produced at the rated rpm & current for the
machine coupled to it. The prime mover becomes the motor under test
& the dynamometer works as generator & its gets loaded by
dissipating voltage generated in resistive load bank. This model is the
industrial/educational model suitable for demonstrating to students the
complete know of the basics, components, mechanicals, loading methods,
torque evaluation, loading scheme, wear & tear & maintenance of
these motors packaged in small rating. Students can make connections of
their own with the help of the terminations provided for study of
features viz coupling the motor to be tested, starting methods,
speed-torque, excitation control of dynamometer, power dissipation of
generator, torque measurement.
