Performance Analysis of Two-phase Induction Motor Operating with Symmetrical Windings Using MATLAB/Simulink

Abstract

This research models and simulates a symmetrical wound Two-Phase Induction Motor
(TPIM). The winding arrangement is obtained by making both the phase winding of main and
auxiliary of the Motor equal in turns, properties, and connected to a Two-Phase Power Supply.
The Power Supply is obtained from an inverter with source either from batteries or a rectified
power supply. The Motor Models are based on induction motor mathematical expressions,
geometric dimension and implemented using MATLAB/Simulink Program. The current,
torque and speed wave forms under no-load and full-load conditions were compared with that
of a Capacitor-Start Capacitor-Run Single-Phase Induction Motor (CSCR-SPIM); the
transient and steady state performance were analyzed. The simulation models created in
MATLAB/Simulink were also compared with laboratory measurements, and the results
showed that the modeled machine is advantageous in its operation as compared to a Poly
Phase Induction Motor. The two-phase induction motor also has characteristic similar to
three-phase induction motor such; heavy starting torque, improved power factor, minimized
torque harmonics and increased power rating.
