“…It is found that the highest temperature in the motor is 87 • C under steady-state and nominal conditions. This result is reasonable for a typical electric motor with similar size [46]. Figure 27 shows the comparison of the torque-current characteristic for the proposed 15-stator-slot motor with and without permanent-magnet skewing.…”

Abstract-This paper presents the design and analysis of an inside-out axial-flux permanent-magnet (AFPM) synchronous machine optimized by genetic algorithm (GA) based sizing equation, finite element analysis (FEA) and finite volume analysis (FVA). The preliminary design is a 2-pole-pair slotted TORUS AFPM machine. The designed motor comprises sinusoidal back-EMF waveforms, maximum power density and the best heat removal. The GA is used to optimize the dimensions of the machine in order to achieve the highest power density. Electromagnetic field analysis of the candidate machines from GA with various dimensions is then put through FEA in order to obtain various motor characteristics. Based on the results from GA and FEA, new candidates are introduced and then put through FVA for thermal behavior evaluation of the designed motors. Techniques like modifying the winding configuration and skewing the permanent magnets are also investigated to attain the most sinusoidal back-EMF waveform and reduced cogging torque. The performance of the designed 1 kW, 3-phase, 50 Hz, 4-pole AFPM synchronous machine is tested in simulation using FEA software. It is found that the simulation results fully agree with the designed technical specifications. It is also found from FVA results that the motor temperature reaches at highest temperature to 87 • C at the rated speed and full load under steady state condition.

“…The thermal source model which is yielded from a magneto-static and DC current flow model, the thermal field's computation is conducted through FEA based on a coupled thermal and fluid-dynamical model. The result from the experiment has proved that rotor core is extremely hotter than expected [40].

Abstract:The Wind Energy Conversion System (WECS) plays an inevitable role across the world. In particular, the attention for Permanent Magnet Synchronous Generators (PMSGs) connected with wind farm is popular. This paper deals with the literature review that describes the recent advances, progresses and innovatory trends on PMSGs for WECS. Comparison between geared and direct-driven conversion systems and the classification of electrical machines used in WECS are discussed. A detailed analysis on the design aspects considering various topologies of PMSGs are encompassed in the literature. The PMSG design and optimization problems are solved by field computation techniques and optimized by using Soft Computing (SC) techniques .The threedimensional, finite element software platform for the analysis and design of PMSGs is discussed. This paper also deals with the interdisciplinary modeling, analysis, and optimization of PMSG using Finite Element Analysis (FEM) and SC techniques. Finally, PMSGs are reviewed and compared for further exploration.

“…Marignetti et al [10] undertook CFD modelling of an AFPM machine using a combined simulation which modelled fluid flow as well as thermal conduction in the solid domain. However, they assume without justification that the flow is laminar, and they use an experimental correlation for the stator heat transfer ('Becker') with no reference to the source of this correlation.…”

Abstract-Relatively little fundamental research has been undertaken on heat transfer in disc type electrical machines, a common example being the axial flux permanent magnet (AFPM) machine. Power density is usually thermally limited and therefore understanding of stator convective heat transfer is crucial in the design of AFPM machines and electrical machines in general. This paper presents direct measurements of radially resolved stator convective heat transfer in a rotor-stator system, using a thin-film electrical heater array to measure heat transfer. The heater array combines surface temperature sensing with heat flux measurement. It is found for the three gap sizes considered here that average Nusselt number (non-dimensional convective heat transfer coefficient) increases from N u ≈ 100 at low disc speeds/rotational Reynolds numbers (Re θmin = 3.7e4) up to N u ≈ 300 − 400 at higher speeds (Re θmax = 5.6e5).
