This paper investigates the potential benefits of utilizing superconducting materials in machines. The project focuses on replacing conventional copper windings with a machine. machine is modelled and simulated using ANSYS software, both windings. A 3.7kw 11kw 3 phase Induction machines are YBCO material applied to stator rotor results show that use can significantly reduce energy losses improv...

Expert systems are used for evaluating the actual state and future behavior of insulating systems of high voltage electrical machines and equipment. Several rule-based expert systems have been developed in cooperation with top diagnostic workplaces in the Czech Republic for this purpose. The IZOLEX expert system evaluates diagnostic measurement data from commonly used off-line diagnostic method...

This paper presents an original software tool based on a model of expert system that has been developed to satisfy the requirements of fault diagnosis, repair and maintenance of electrical machines in industrial, educational or other applications. This software comprises an SQL server database and provides different user levels (simple user, power user and administrator). By the introduction of...

Multisector machines reveal a high fault-tolerant capability, since failure events can be isolated by de-energizing the faulty sector, while healthy ones contribute in delivering required power. This article is focused on thermal analysis of multisector three-phase and operations. First, 3-D lumped parameter network (LPTN) single sector developed finetuned against experimental data, through gen...

This contribution introduces a vector interpretation to unify the description of torque development in rotating electrical machines. The motivation behind this attempt is necessity applying different physical and calculation methods, such as Lorentz force, Maxwell stress tensor, co-energy methods etc., for predicting estimating components, e.g. synchronous torque, oscillating cogging reluctance...
