To improve the power density and reliability of radial (RS-TLPMG) and quasi-Halbach (QH-TLPMG) magnetization tubular linear surface-mounted permanent magnet generators under realistic sea-state conditions, a novel tubular linear generator with multilayer interior permanent magnets (MI-TLPMG) for wave energy conversion is proposed and analyzed in this paper. Using finite element analysis (FEA), a comprehensive comparison of air gap flux density, flux linkage, back electromotive force (back-EMF), load, and no-load performance is investigated to verify the advantages of the proposed machine. The FEA results indicate that MI-LTPMG with a flux-concentrating effect has higher back-EMF, air gap magnetic flux density, flux linkage, and output power than do the other two machines. Finally, a prototype is manufactured and measured on the test platform and wave tank. The experiment and simulation results show a great agreement with each other.

“…The IPMSM's maximum output pow Among the most important decisions during the design stage is the selection of the iron bridges size, as it substantially affects the IPMSM's back-emf and the magnetic flux leakage [27]. The findings of the work presented in [28] indicated that the d-axis inductance varies with the iron bridges saturation level.…”

The extreme environmental issues and the resulting need to save energy have turned attention to the electrification of energy applications. One of the key components involved in energy efficiency improvements is the appropriate conception and manufacturing of electric machines. This paper overviews the electromagnetic analysis governing the behavior of permanent magnets that enable substantial efficiency gains in recent electric machine developments. Particular emphasis is given to modeling the properties and losses developed in permanent magnets in emerging high speed applications. In addition, the investigation of properties and harmonic losses related to ferromagnetic materials constituting the machine magnetic circuits are equally analyzed and discussed. The experimental validation of the implemented methodologies and developed models with respect to the obtained precision is reported. The introduction of mixed numerical techniques based on the finite element method intended to appropriately represent the different physical phenomena encountered is outlined and discussed. Finally, fast and accurate simulation techniques including aggregated lumped parameter models considering harmonic losses associated with inverter supplies are discussed.

“…With the development of electric vehicle (EV) technology, inwheel motors have been considered as the ideal candidates since short mechanical transmission chain, high transmission efficiency and strong mobility [1][2][3]. However, in order to meet the demand of EVs performance, the in-wheel motors need have high efficiency, high torque density, wide-speed-range capability, and low torque ripple.…”

This article presents a new rotor with fractional slot distribution winding permanent magnet (FSDWPM) machine to improve the torque density of in‐wheel motor. In order to achieve the high torque/power density and reduced material weight with constrained rotor inner diameter and stator outer diameter, three traditional rotor topologies, including single‐layer V‐shaped, double‐layer V‐shaped, and delta‐type, are selected and compared with the proposed FSDWPM machine. Subsequently, the corresponding basic electromagnetic performances, including open‐circuit back‐EMFs, on‐load torque, and efficiency distributions, of the four machines are investigated and compared by finite element (FE) analysis. The simulated results shows that the proposed rotor arrangement exhibits the highest average torque, excellent field‐weakening capability, the largest high‐efficiency region compared with conventional rotor structures. Finally, a 50 kW FSDWPM machine prototype with double‐layer PM arrangement is manufactured, and some experimental results are conducted to confirm the feasibility and effectiveness of the proposed design.
