The article describes the possibilities of employment of external magnetic field for detection of rotor eccentricity and for bearing fault diagnosis. Proposed method uses the magnetic flux density in proximity of induction motor as a diagnostic signal and it reaches the relativel ...
This paper describes distance laboratory for automotive electrical engineering. Designed system allows system identification and parameter tuning Learning objectives are clearly defined and their verification is included too. Designed distance laboratory provides the user with a ...
Current development trends regarding mobile electrical-generator sets (EGSs) indicate that enhancement of efficiency is to be sought in means to operate the driving engine (either diesel or gasoline) continuously at its optimum speed. The engine-generator dynamics at a sudden loa ...
The paper presents an overview of the current state of development of distance and virtual laboratories in Electrical Engineering with a special attention to the fields of Power Electronics and Electrical Drives. Based on a broad overview of the open Internet resources from field ...
PEMC WebLab features online experiments sponsored by the EU. Several real-world experiments aim at students and engineers of electrical engineering and mechatronics who want to extend or refresh knowledge. The Power Quality and Shunt Active Filters experiment is presented. The pa ...
New generation of mobile electrical power sources is based on the historical change from constant speed, determining the required frequency, to the optimally changed engine and generator speed. The constant frequency and required voltage value is achieved by means of power electr ...
