DC Dynamometer for Motor Testing

DC Dynamometer for Motor Testing .
DC Dynamometer for Motor Testing 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.
