چکیده :

Due to their numerous advantages, induction motors (IMs) have garnered significant interest over the years. Addressing the critical issue of reducing energy consumption, optimizing electric motors remains a paramount concern. However, the presence of Ohmic losses in the rotor cage of IMs limits their efficiency. In recent years, several studies have explored replacing IMs in fan and pump applications with alternative electric motor types to enhance efficiency. One promising option is the line-start permanent magnet-assisted synchronous reluctance motor (LS-PMaSynRM), which can achieve IE4 and potentially the upcoming IE5 efficiency classes for the same output power compared to IMs. This work extends the authors' previous efforts in implementing LS-PMaSynRMs for fan and pump applications. The paper focuses on rotor design using three-dimensional finite element analysis (FEA) and the standard prototyping process of an LS-PMaSynRM for pump applications. A benchmark 0.75kW-1500rpm IM is considered, with its rotor replaced by the newly designed rotor. The finite element analysis results are presented and discussed. Simulation results are further validated through experimental prototyping and testing of the case-study motor. Finally, the performance characteristics of the prototyped motor are compared with those of a counterpart IM.
