Special Issue Information

Dear Colleagues,

We are pleased to announce this Special Issue on the topic of “Modern Aspects of the Design and Operation of Electric Machines”. Electric machines perform very important tasks in the modern world, both generating electricity and driving many devices. Therefore, new technologies used in electric machines to improve their parameters are particularly desirable. Additionally, various aspects concerning electric machine operation and their design optimization are of the greatest importance. These aspects include issues related to the design of an electrical machine, such as the selection of appropriate materials and optimization of the construction of electric machines. They also cover all issues related to the operation of electrical machines, such as diagnostics of the effect of power quality disturbances, low-quality voltage supply, or new methods of detecting and preventing the electrical machines malfunctions.

For this Special Issue, we encourage the submission of original contributions and review papers regarding all modern aspects of design, operation of electric machines and power-quality-related phenomena in all types of electric machines. Potential topics may include, but are not limited to design, optimalization, and new technologies used in electric machines.  In addition, any aspects related to reliability and durability of electrical machines, the generation of power quality disturbances by electrical machines, proposals of modification of power quality standards and rules in order to protect electrical machines against malfunctions due to excessive power quality disturbances.

Vibration monitoring plays a crucial role in assessing the condition and operational safety of electric drive systems. In many industrial applications, scalar control is widely used due to its simplicity and reliability, yet its influence on vibration transmission within interconnected machines remains insufficiently explored. This study addresses the problem of understanding how mechanical vibrations are transmitted between a scalar-controlled induction motor coupled with an AC generator. A comparative experimental investigation was conducted using two different configurations of drive units, incorporating either an induction or a synchronous generator. Vibrations were measured at various operating speeds and analysed using different sensor types to ensure repeatability and reliability of the results. The findings have revealed distinct patterns of vibration transmission between the motor and generator, highlighting the importance of drive system configuration and measurement methodology. A novel approach to data presentation is proposed by normalising vibration levels between machines, offering a clearer interpretation of vibration amplification or damping effects. The results contribute to the development of diagnostic techniques and the optimisation of scalar-controlled drive designs. Full article
