EDDY CURRENT DYNAMOMETER FOR MOTOR TESTING:

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 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)

Technical Specifications:

• Power ratings available       : 1KW / 2KW/ 5KW/ 10KW
• Voltage Input                    : 230V AC to Exciter unit.
• Rpm of Machine                 : 1500
• Single shaft extension, SPDP, IP23, IC01, B3, Class-B, S1, Solid yoke
