The rotating mechanical systems comprise several rotor machines and mechanisms which are widely applied in various domains of industry including electrical energy production, means of transportation, aerospace, household, and many other devices of everyday use. Their main common feature is the basic working tool under rotational motion. This motion is usually associated with numerous physical phenomena which can more or less intensively interact with each other. Further knowledge about these systems is still required to make the operation more effective, robust, and environmentally friendly.

The rapid development of new technologies presents new challenges for constructors and operators of rotating machines and mechanisms. There is a need for on-line fault diagnostics and identification, control of efficient and safe operation, reduction of vibration and noise, and many others. For this purpose, the research society is expected to develop increasingly advanced theoretical and experimental methods necessary to improve the already existing structural and technological solutions as well as to create completely new designs of rotating systems together with their operational equipment. Several rotating mechanisms and devices co-operate with various electric machines. They can be driven by electric motors of various types, or they can drive generators of electric current. As a result, the mechanical and electrical parts of the entire rotating system interact dynamically with each other.

The aim of this Special Issue is to bring together original research articles and review articles in the field of dynamic electromechanical interactions in rotating systems. We hope that this Special Issue will highlight the problems encountered in the theory and practical operation of machinery and mechanisms that have not been sufficiently explored. Submissions can come from academics and engineers working in the industry. We welcome interdisciplinary research in electronics, electro-technics, information technology, automatics.

Potential topics include but are not limited to the following:

• Dynamics of electrical machines
• Vibration control in electromechanical systems
• Diagnostics and fault identification in electromechanical systems
• Electromechanical interactions in rotating machinery systems
• Health monitoring of electromechanical rotating systems
• Monitoring of electrodynamic phenomena in wind turbines
