Designing Reliability into Rubber and Plastic AC Motor Control Equipment

The reliability of rubber mill control is achieved by the recognition of the operational and environmental needs of the equipment. Mature design, quality of material and workmanship, and ease of maintenance are intrinsic to the nature of a reliable product. This paper defines reliability, discusses the need to achieve it, and demonstrates its measurement and attainment in the process of preparing a product for manufacture. Practical examples are provided to demonstrate how the selection of basic materials, components, enclosures, and circuit arrangements enhance reliability.
