Improving Performance and Prolongation of Electric Motors by Advanced Control Scheme in Nigeria Manufacturing Industry: An Issue to Sustain Production and Marketing of Industrial Products

Abstract

Most manufacturing industries in Nigeria operates electrical machines for industrial processes without optimizing the performance of the electric motors used by them. Poor control and maintenance of these motors has led to unsustain production due to the failure of the motors. The  objective of  the study is to  illustrate how feedback control  system can be use to prolong electric motors life-span, point  out  the need  to analyze electric motors aided by computer simulation via modeling of motor parameters  that can translate to  hardware  implementation aim at improving their performance and point out ways by which  revenue can be generated from  the sales of electric motors.  The study employed a contents analysis base on relevant data gathered from journals, books, websites and compiled database which were analyzed to give a complete understanding of the possible causes of electric motor failures in Nigerian manufacturing industries. The findings reveals that poor performance and reduced life-span is as a result of zero or poor control of the electric motors. Using advance control system approach aided by computer simulation application compared to the conventional method of control of electric motors entails modeling, analyzing and controlling electric motors using orthogonal dq-axis transformation of the electric motor phase windings. The study concluded that to sustain production in Nigeria manufacturing industries using feedback control system application to electric motors will improve their performance and prolongation. The study recommended that adequate sensitization should be carried out by the manufacturing association of Nigeria (MAN) on the need to optimize electric motors usage in industries and adopt the advance control strategy.
