DC DYNAMOMETER FOR MOTOR TESTING





Description:

 

DC 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 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 me thods, 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.

 

Technical Specifications:

  • Power ratings available     : 1KW / 2KW/ 5KW/ 10KW
  • Voltage Input                   : 230V DC
  • RPM                                 : 1440 / 2880 RPM,
  • Single / Double shaft extension, SPDP, IP23, IC01, B3, Class-B, S1, Solid yoke.
