This study aims to empirically investigate the impact of sustainable manufacturing practices (SMP) on sustainability performance (SP) among manufacturing firms in Malaysia. Drawing from the theoretical lenses of stakeholder theory, the present study advocates the three pillars of sustainability, encompassing economic, environmental, and social sustainability, in measuring firm performance. Using PLS-SEM approach, the survey data collected from 150 firms were analyzed. The findings reveal that both underlying variables of SMP, internal SMP and external SMP, have positive and significant impact on environmental and social sustainability. Surprisingly, while internal SMP proof the significant positive influence on economic sustainability, external SMP failed to do so. Theoretically, the study contributes to the sustainable manufacturing literature by demonstrating the relationship between SMP and sustainability performance (SP). Practically, the study is beneficial for practitioners in understanding the diverse aspects of SMP and SP, identifies the strengths and weaknesses of their current SMP, and provides a guideline in improving their performance. © 2016 Penerbit UTM Press.

Bearingless permanent magnet synchronous motor (BPMSM) combines the characteristic of the conventional permanent magent synchronous motor and magnetic bearing in one electric motor. BPMSM is a kind of high performance motor due to having both advantages of PMSM and magnetic bearing with simple structure, high efficiency, and reasonable cost. The research on BPMSM is to design and analyse BPMSM by using Maxwell 2-Dimensional of ANSYS Finite Element Method (FEM). Independent suspension force model and bearingless PMSM model are developed by using the method of suspension force. Then, the mathematical model of electromagnetic torque and radial suspension force has been developed by using Matlab/Simulink. The relation between force, current, distance and other parameter are determined. This research covered the principle of suspension force, the mathematical model, FEM analysis and digital control system of bearingless PMSM. This kind of motor is widely used in high speed application such as compressors, pumps and turbines. © 2015 Institute of Advanced Engineering and Science. All rights reserved. Source
