Energy efficient drive system for domestic and agriculture applications: A comparative study of SPIM and SRM drives

Domestic appliances employing electrical energy are becoming more demanding in terms of increased efficiency and improved functionality. Commonly used home appliances such as mixer-grinders, food processors and water-lifting pumps are low cost-technology products, sold in high volumes. Hence efficiency improvement in this area results in larger savings of energy, which is extremely important in the context of sustainable development. The Single Phase Induction Motor (SPIM) is one of the major workhorse in such applications. This paper examines the possibility of utilizing Switched Reluctance Motor (SRM) in such applications. The paper mainly focuses on the energy efficiency of SPIM and SRM including the control aspects of both drives. Analytical and Finite Element Methods (FEM) are employed for the designing of the motors which are further validated through experiment. It is clear from the results that, SRM gives better performance in terms of energy efficiency and speed control as compared to the commonly used SPIM Drive and hence is a better alternative in view of energy conservation.
