Introduction :
- 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 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 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)
