Abstract

This study discusses about an exact and novel scheme for Rotor Field Oriented Control (RFOC) method in single phase Induction Motors (IMs) with two different main and auxiliary stator windings. In the presented technique, rotational transformations are introduced and applied to the single phase IM equations. It is proved by using these proposed rotational transformations, asymmetrical equations of single phase IM changed into symmetrical equations. As a result, with some modifications in the conventional field oriented controller, vector control of single phase IM can be done. Results are presented to show the good performance of the presented technique.

Highlights

Single phase Induction Motors (IMs) are broadly used in the low power domestic and industrial applications where a three phase AC supply is not available
This study shows the single phase IM can be modeled as a balanced circuit
PROPOSED METHOD FOR VECTOR CONTROL OF SINGLE PHASE IM. As it was mentioned before by using of conventional rotational transformation, the backward terms is generated in the Rotor Field Oriented Control (RFOC) equations of single phase IM

Summary

INTRODUCTION

Single phase Induction Motors (IMs) are broadly used in the low power domestic and industrial applications where a three phase AC supply is not available. One of the drawbacks in the presented FOC method by researchers for single phase IMs is that, with supposition of Lqs/Lds = (Mq/Md)2 = a2, coupling between stator main and auxiliary inductance in single phase IMs is not considered (Azza et al, 2011; de Rossiter Corrêa et al, 2000, 2004; Jang, 2013; Jemli et al, 2009b; Reicy and Vaez-Zadeh, 2005; Vaez-Zadeh and Harooni, 2005) Using of this assumption is reflected in the speed and the torque responses of the drive system. By controlling of forward and backward components, controlling of single phase IM can be done but the controlling structure for single phase IM will be complex
