“…Asystematic solution of Maxwell's equations is used to calculate magnetic flux density by PMs in the midpoint of mechanical air-gap region. It offers the comparison between analytical and numerical (FEM) solutions of back EMF using Faraday's law [113]. Themistoklis Kefalas, et al, (2005) study the performance of PMSG and the rotor skew effects in PMSG.…”

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.

In IT business, the capacity of the battery in smartphone was drastically improved to digest various functions such as communication, Internet, e-banking, and entertainment. Although the capacity of the battery is improved, it still needs to be upgraded due to customer's demands. In this article, we optimize the design of the linear generator with the Halbach array to improve the efficiency of harvesting vibration energy during human walking for the battery capacitance. We propose the optimal design of the tubular permanent magnet with the linear generator that uses a Halbach array. The approximate model is established using generic algorithm. Furthermore, we performed electromagnetic finite element analysis to predict the induced voltage.

“…there is no starting and cogging torque what is very important especially for wind power systems. Moreover, it is cheap, easy to manufacture, and can be produced in the range of single watts up to hundreds of kilowatts of power in multi-disk operation ( Javadi and Mirsalim, 2008;Chan and Lai, 2007;Virtic et al, 2008;Hosseini et al, 2008;Hwang et al, 2009 It is resistant for short-time overload because of air-core which is free of saturation. The biggest drawback is a need of use stronger magnets to obtain the same power like in conventional iron-core machine which is the reason of higher reluctance of magnetic circuit.…”

Purpose -This article seeks to present the simple and easy to manufacture design of a permanent magnet generator based on coreless windings. An example is shown of basic calculations based on an equivalent magnetic circuit. Finally, a description of a 20 kW prototype of PMSG is presented based on rectangular magnets which contains mechanical design and experimental results. Design/methodology/approach -The analysis presents flux dependence using several parameters such as: magnet's grade and size in comparison with coil and air-gap dimensions. The second part of the article concentrates on simulation results of Finite Element Method analysis (FEM) that clearly shows the flux distribution for different magnet shapes -trapezoidal and rectangular.Findings -The presented topology of the machine has several advantages, e.g. there is no starting and cogging torque which is very important especially for wind power systems because of the start up point of the turbine. Moreover, it is cheap and easy to manufacture because of ironless technology in stator. The generator can be produced in the range of single watts up to hundreds of kilo watts of power in multi disk operation.Research limitations/implications -The ironless technology applied to the stator, results in the need for using stronger magnets in comparison with a classic iron-core permanent magnet machine. Practical implications -This axial-flux machine seems to be very interesting for low speed power generation systems such as wind and water turbines. Cost effective permanent magnet generator can be used for local power generation (e.g. heating). The generator can also be connected to the main grid through a special grid-tie-inverter. Originality/value -The article presents the simple and rarely presented topology and describes a few methods of optimisation of the parameters to achieve maximum power.
