Abstract

Rapid industrialization of the industrial sector for development of the nation has led to an ever-increasing demand of electrical energy. With the various problems involved in the execution of power projects, the ever-widening demand-supply gap of electrical energy has led to energy crisis year after year. The industrial sector consumes over 50 % of the total energy generated for consumption. With rising costs of electricity supply, it has now become one of the single largest variable cost in determining the cost of production per unit. The inability of industrial sectors to switch over to energy consuming equipments has also not helped the situation. The only solution to the present day energy crisis is energy conservation rather than energy generation. With the technological advances made in the constructional features of electrical equipments, use of energy efficient equipments is very advantageous. Though the cost of energy efficient equipments may be slightly heavy at first, use of such equipment in the long run is beneficial to both the power utility as well as the consumer. Among the various equipments used in the industrial process, electric motors constitute 75 % of all energy consuming equipments, among which 90 % of them are ac motors. The various points to be considered for an electric motor are its losses, efficiency, operating power factor and the load requirements. This paper attempts to bring out the importance of the above factors in motor selection with suitable examples and quantifies the saving that can be achieved by way of demand and energy savings
