EDDY Current Dynamometer for Motor Testing For Electrical Lab Training Description and Specifications for Lab Tenders
EDDY Current Dynamometer.
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 an eddy current
dynamometer is 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 Eddy current clutch
provided in the dynamo with the help of an exciter unit. 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, torque measurement.
(Providing load cells is an option)
