Efficiency and Motor Performance Evaluation of Three-Phase Induction Motor

Vicky Panchal, Abhishek Kumar Singh, Rakesh Joon

Abstract


The study concerns with industrial low voltage three-phase induction motors, 4 pole, 50 Hz,
400 V, TEFC, in the 0.75–22 kW power range. The paper presents the results of a research
project whose aim was the efficiency enhancement in industrial three-phase induction
motors, making use die cast copper rotor cage and premium electrical steel. Induction motor
is a veritable machine in the industries today, since is the most widely used electric motor in
the industry. It offers a reasonable performance, manageable torque/speed characteristics
and a better efficiency. The aim of this paper is to examine a comparative analysis of a threephase
induction motor for performance evaluation. The computer simulation and
experimental methods were used to carry out the investigations, validation and evaluation of
the behavioural characteristics of the machine. The simulation and experimental results
obtained were compared to validate the results obtained from the experimental method. It
was shown that the results from the simulation and experimental methods were in agreement
with the theoretical values of the three-phase induction motor. Thus, the results indicated that
the relative errors were negligible and the proposed simulation models accurately predict the
equivalent circuit parameters of the induction motor.
