Smart Motor

The goal of this project is to investigate how to improve the starting, synchronization, and synchronous operation modes of LS-SynRMs by dynamically adjusting the magnetizing flux level through connection-mode self-switching of optimized multiflux winding configurations under ideal and unideal load and supply voltage conditions. For example, a medium/high flux level during starting and synchronization to boost the cage-induction torque, and a low/medium flux level to maximize the efficiency and power factor at synchronous operation. Additionally, microcontroller-based per-phase overcurrent protection and condition monitoring algorithms will be exploited and tested. The PI has a long experience in designing and optimizing multiflux winding configurations, as well as implementing solid-state solutions to automatically change the winding connection mode. The power electronics module of the device for the self-management of the connection mode will be based on wide-bandgap SiC semiconductors to reduce conduction losses in the bidirectional solid-state switches, which are the base for the connection mode change. Two innovative solutions are expected to come out from this exploratory project: (i) optimized multiflux winding configurations and the respective connection mode management; (ii) embedded smart electronic connection-mode switching device. The integration of these two solutions into existing/commercial LS-SynRM will enhance its full-load and part-load efficiency and power factor, starting and synchronization effectiveness, and active winding protection. This translates into better performance, higher robustness, and expanded applicability, which may potentially accelerate its penetration in the industrial sector. On top of it, the proposed self-adapted LS-SynRM will have self-monitoring, self-protection, and wireless communication capability, perfectly fitting into the modern industry paradigms (Industry 4.0/5.0). If the goals of this project were successfully achieved, they may define the next generation of industrial LS-SynRMs.
