This article seeks to describe the implementation of a problem-based learning (PBL) teaching-learning method in a university classroom. The aim is for the stu-dent through given real-life situations to acquire knowledge, abilities, and atti-tudes in the s... see more

Numerical simulation softwares are used for research and teaching, to allow a good comprehension of the systems under study before practical implementations. In electrical machines modelling, the resulting system of differential equations are usually non-... see more

Electricity markets are considered to be the most volatile amongst commodity markets. The non-storability of electricity and the need for instantaneous balancing of demand and supply can often cause extreme short-lived fluctuations in electricity prices. ... see more

Condition and health monitoring of electrical machines during dynamic loading is a common, yet challenging problem in main battle tanks. Existing methods address this issue by extracting various features which are subsequently used in a classifier to isol... see more

Electricity markets are considered to be the most volatile amongst commodity markets. The non-storability of electricity and the need for instantaneous balancing of demand and supply can often cause extreme short-lived fluctuations in electricity prices. ... see more

Maintenance of electric machines and installations is a particularly important area; eventual faults in these devices may lead to significant losses in terms of time and money. The investment and concern in developing proper maintenance protocols have bee... see more

The analysis of dependence of the magnetic losses in hauling electric motors on the frequency of armature remagnetization is presented. A universal characteristics of the magnetic losses reduced to the frequency of remagnetization of 50 Hertz is offered.

The conditions of providing the mutual loading of DC electric machines are considered.

The analysis of power streams in the schemes of mutual loading of hauling electric machines of direct and pulsating current is presented.
