A fault indicator, the so-called swing angle, for broken-bar and interturn faults is investigated in this paper. This fault indicator is based on the rotating magnetic-field pendulous-oscillation concept in faulty squirrel-cage induction motors. Using the "swing-angle indicator," it will be demonstrated here that an interturn fault can be detected even in the presence of machine manufacturing imperfections. Meanwhile, a broken-bar fault can be detected under both direct-line and PWM excitations, even under the more difficult condition of partial-load levels. These two conditions of partial load and motor manufacturing imperfections, which are considered as difficult situations for fault detection, are investigated …

Thai manufacturing SMEs have played a major role in developing Thai economy, social and employment. In this situation, they have been confronted by forceful overseas competitors, especially in lowcost producers such as China, India, Vietnam, etc. They need to upgrade organisational performance in order to increasing their international competitiveness. However, most of Thai manufacturing SMEs have been inadequate modern technology when compared to large enterprises. Therefore, management technique i.e. TQM has been introduced to implement in Thai manufacturing SMEs for establishing a good quality management system, developing human resources and increasing business performance. The questionnaire was used as a tool …
