“…Different analytical models including MEC [23] and WF models [21] have been proposed for analyzing electric machines. Compared with FEA, these models are not accurate enough because, both MEC and WF consider only the normal component of the field.…”

Small wind turbines can generate clean energy in diverse locations, from urban centers to rural areas without access to the main grids. This study proposes design optimization of an axial flux permanent magnet (AFPM) synchronous machine for small scale portable applications. At first, a fast, accurate and pragmatic hybrid analytical model is proposed for performance prediction of the machine. The proposed model is then used as a basis for a direct search optimization process with factual constrains and objective functions to improve the machine in terms of efficiency, weight and to ease the manufacturing process. 3 Dimensional Time Stepping Finite Element Method (3-DTSFEM) is utilized to validate the accuracy and effectiveness of the proposed model and optimization methodology.Output characteristic of the machine from both analytical model and 3-DTSFEM are compared to each other that proves the functionality of the proposed study.

“…But this method is not very accurate due to poor estimation of the equivalent circuit parameters. Different analytical models, like Winding Function (WF) [21][22], Magnetic Equivalent Circuit (MEC) [23], and Fourier series method [24] are developed for design and optimization of electrical machines.…”

“…This said, the authors underlined the fact that during the operation of aircrafts jet pipe electro-hydraulic servo valves, most rated currents of the torque motors are within 50 mA for which the magnetic circuit has a linear behavior. In [7], Saneie and Nasiri-Gheidari proposed a MEC model of an outer-rotor single phase squirrel cage induction motor. Beyond the rotor position, the developed MEC takes into account the rotor slots' skewing, the stator end windings, the slot leakage flux, and the magnetic saturation.…”

3D Rotor Position-Dependant MEC Modeling of Different Claw Pole Machine Topologies

The paper is aimed at a 3D magnetic equivalent circuit (MEC)-based modelling of claw pole synchronous machine topologies. Beyond the magnetic saturation and the armature magnetic reaction, the proposed modelling approach takes into consideration the rotor position variation, yielding the socalled: rotor position-dependant MEC. Accounting for the complexity of the magnetic circuit of claw pole topologies, specific assumptions are adopted prior a general analytical derivation of their MEC models. The developed analytical approach focuses on the air gap reluctance under variable rotor position considering a simplified geometry of the claw. A dedicated numerical procedure based on the Newton-Raphson algorithm is proposed for the resolution of the designed rotor position-dependant MEC. The proposed approach is applied to three claw pole topologies. The two first ones are equipped with a single source of excitation achieved by a field. Their analytically-predicted features are validated by experiments. The third topology has a dual excitation achieved by a field and permanent magnets (PMs) in the rotor. Its analyticallypredicted features are validated by 3D finite element analysis (FEA). It is found that both experimental and FEA results are in quite good agreement with the analytical predictions yielded by the proposed rotor position-dependant MEC.INDEX TERMS Armature magnetic reaction, claw pole topologies, magnetic saturation, no-/on-load features, rotor position-dependant magnetic equivalent circuit, single/dual excitation, three dimensional finite element analysis.

“…However, with such a large skew angle, the current induced in the bars of SPIMs reduces drastically. There has been little literature on the outer rotor SPIMs for ceiling fans in the past [5]. Moreover, for ceiling fan application, there has not been much research in SPIMs [6][7][8].…”

This paper deals with the robust design of a single‐phase induction motor (SPIM) for ceiling fan application. It also identifies the critical design parameters of a single‐phase induction motor for an outer rotor geometry. The inaccuracy issues in the equivalent circuit method for such low watt application, are discussed with experimental validation using different equivalent circuit approaches. Moreover, the finite element (Finite Element) approach is used for the accurate design of the SPIMs. The magnetic behaviour of the ceiling fan SPIM is also studied in detail. A 45 W ceiling fan design is considered for improvement in the efficiency and performance with the same outer and inner diameter dimensions. For the improved design of the SPIM, a sequential DoE (Design of Experiments) based methodology is used. Taguchi's orthogonal arrays, namely L18 and L9, are used for robust design of the stator as well as the rotor. The improved design for ceiling fan SPIM is validated by two‐dimensional time stepping transient FEA.
