NettetFor safety-critical applications, such as in the aerospace, automotive and transportation fields, electrical machines need to be highly reliable. The reliability of an electrical machine is mostly limited by the life of the insulating materials used to wound its stator, which ensures that an electrical short do not occur during the entire service life. Nettetdecrease the)insulation resistance. As a result, a moderate barrier height 𝜙(0 (and therefore a moderate IR value) with a longer MTTF (smaller degradation rate constant 𝐾) will result in a minimized IR degradation process and the most improved reliability in Ni-BaTiO 3 multilayer ceramic capacitors. NettetNECI has created a reliability program that offers predictive maintenance services, consulting services, and the industry’s best products to help clients improve plant reliability.
