Abstract:
The paper presents the dynamic analysis of two phase induction motor with symmetric and orthogonal phase windings. The proposed motor winding arrangement is obtained by making the main and auxiliary windings of a single-phase induction motor equals in all parameters, and connected to a two-phase power sources. The two-phase supply is obtained from the conventional single-phase power supply by using a two-phase inverter drive. Based on geometric dimensions, the model was created using 2D ANSYS Maxwell Finite Element Analysis Software. The transient and steady state analysis of the machine currents, electromagnetic torque and speed on no-load and full-load condition were observed and compared with that of capacitor-start capacitor-run single-phase induction motor. The proposed mode of operation allows the single-phase induction motor with two equal stator windings to gain the advantages of the poly-phase induction motor such as heavy starting torque, improved power factor, less torque harmonics and higher rated power.
