EFFICIENCY IMPROVEMENT OF THREE PHASE SQUIRREL CAGE INDUCTION MOTOR BY CONTROLLING THE APPLIED VOLTAGE TO THE STATOR
Abstract: Optimizing the efficiency of three
phase squirrel cage induction motors
(SCIMs) plays a big role in saving
electric energy consumption. The aim
of this thesis project is to operate a
three phase SCIM with maximum
allowable efficiency at light loads by
controlling the applied voltage to the
motor using MATLAB/SIMULINK.
Mathematical analysis and parameter
identification of three phase SCIM are
explained. Because of its simplicity of
use, MATLAB/SIMULINK is employed
to determine motor parameters and to
simulate a three phase SCIM under
different loads. The effect of voltage
variation on motor characteristics
such as motor current, torque, speed,
power factor, and efficiency in stable
and unstable regions of operation is
explained. A comparison between
conventional operation and maximum
efficiency operation is performed.
