Design and Development of Motor Characterization Test Bed /

Abstract

AC Motor constitutes 60-70 percent load on any country’s National Grid. If AC motors are made efficient, then most the losses on the electric grid can be minimized. Pakistan’s overall losses are about 25 percent, which are quite high as compared to other countries in the world. Core of this problem is reducing the losses by making load management (demand side management) by cutting down losses resulting from inefficient motors. Motor characterization test bed will characterize the motor according to NEMA and IEC curves and certifies for Minimum Energy Performance Standard (MEPS) for running the motor. In this way state of the art testing and development system is introduced with cost and efficiency optimization i.e. indigenous design of whole system down to the component level like sensors and recovery of the generated energy of dynamometer to be injected to the drive of motor under test. The experimental results verify the efficiency improvement of the testing system.
