Abstract:

This article focuses on modeling of an Axial Flux Permanent Magnet Generator (AFPMG). The authors analyzed selected variants of disk generators, including coreless stator constructions and with iron core ones, also taking into account the Permanent Magnet (PM) arrangement in order to show the way to obtain the optimal machine characteristics based on analytical equations. In addition to the full model, which takes into account the higher harmonics of the magnetic field distribution, the paper presents a simplified mathematical model developed for generator operation cases such as standalone, c

This article addresses dual rotor axial flux Ferrite permanent magnet (PM) generator, as an alternative to a surface mounted and spoke types Nd-Fe-B generator which have concentrated windings. The performance parameters of all generators, particularly the efficiency, are identical. The design objective function is the generators mass minimization using a population-based algorithm. To predict the performance of the generators a finite element (FE) technique is applied. Besides, the aims of the design include minimizing cogging torque, examining different rotor pole topologies and different pol

In this paper, a rigorous and efficient approach, using the fuzzy-Inference Taguchi method with the multiple performance characteristics index (MPCI), is employed for obtaining the rigorous design of a small-scale direct-drive coreless axial-flux permanent-magnet (AFPM) generator for a vertical-axis wind turbine (VAWT) with both larger induced voltage and higher efficiency.

Wind power has been recognized as one of the important green energy resources in Taiwan. However, installing large-capacity wind generators needs to meet many environmental regulations, limiting the penetration of wind power to households/communities. In this paper, the design of a novel double-deck vertical-axis wind generator for households is presented, hoping “many a little makes a mickle” and making better use of green energy to reduce carbon emission.

The results of numerical and experimental studies of an electric generator with permanent magnets and axial magnetic flux for low-power wind turbines are presented. In order for wind turbines to successfully compete with sources of autonomous power supply based on solar energy, it is necessary to reduce the specific cost of electric generators. One of the possible ways to reduce the cost of a wind turbine is to replace a quiet-running multi-pole generator with a high-speed one, which is paired with a magnetic step-up gear.

Abstract:

The main converter of mechanical wind energy into electricity in wind turbines is an electric generator. Typically, such systems use synchronous generators with permanent magnets on the rotor. The main disadvantage of this design is the complexity or the impossibility of adjusting the output parameters of the generator: voltage, power, etc. Known methods and tools aimed at solving this problem relate to cases where the wind speed is constant, ie constant. In real conditions, the nature of the wind is changeable. The average annual wind speed for Ukraine varies between ≈ 5-6 m / s. The current

Abstract:

Electromagnetic energy harvesters have been used to capture low-frequency vibration energy of large machines such as diesel generators. The structure of an electromagnetic energy harvester is either planar or tubular. Past research efforts focus on optimally designing each structure separately. An objective comparison between the two structures is necessary in order to decide which structure is advantageous. When comparing the structures, the design variations such as magnetization patterns and the use of yokes must also be considered. In this study, extensive comparisons are made covering all

Abstract:

Influences of three typical vortex generators on flow pattern and ensuing heat transfer augmentation were investigated and compared at similar Re and swirl numbers inlet conditions. Studied swirlers such as propeller swirlers, jet-type swirlers, and rotating honeycombs were installed at the pipe inlet. Reynolds number ranges from 10000 to 30000. Swirlers were set on the swirl numbers 1.4, 0.89, and 0.52, which were obtained by propellers. This study has been carried out under uniform heat flux condition and air was employed as the working fluid. The obtained results provide the individual effe

This paper reports on the design and research on the micro generator. A micro axial-flux electromagnetic generator is designed as size of Φ6mm×3mm. The formulas for air density and induced Electromotive Force (EMF) were given by a magnetic circuit analysis and main design parameters of the micro generator were determined. Numerical simulation was used to analyzed the induced EMF, when the rotation speed is 10kr/min, the induce EMF in one phase is 12.57 mV; the sum of output power is 296.07μW. The results suggest that the micro generator has an ideal output, which means that the generator may b
