On the Optimization of Halbach Arrays as Energy Storage Media
In the paper presented here the optimization of Halbach arrays as storage media for mechanical potential energy is investigated with numerical simulations using FEMM and analytical calculations using the Maxwell stress tensor. Two opposing Halbach arrays form a “magnetic spring” and mechanical potential energy is stored when this structure is compressed. It is here seen that the wavelength of t...
متن کاملOn the Suitability of Using Halbach Arrays as Potential Energy Storage Media
In the work presented here, the suitability of an unusual energy storage medium is investigated. The energy storage system is based on the forceful compression of two magnetic Halbach arrays. The mass and volume energy density is obtained and compared to existing common energy storage systems. The charge and discharge times and depths are also discussed. In addition, limits and considerations, ...
متن کاملElectrical Energy Storage on the Hybrid Grid of Renewable Energy System Using Fuzzy Controller Optimization Algorithm
The main risks of arising from the using fossil fuels can be referred to environmental pollution, the effects of greenhouse gases, climate change and acid rain. For this reason, efficient use of energy in economic development has always been considered as an important goal of sustainable development. In this study, the effects of time-varying electricity prices in the energy storage components ...
متن کاملTemperature-dependent Demagnetisation of Segmented Halbach Arrays
Temperature degrading of magnet material is of mayor interest in many applications. Segmented rare earth Halbach arrays are subject to an augmented temperature degrading effect due to local demagnetisation. This paper presents results using a parameter-based material demagnetisation model. Measurement results of high temperature Halbach arrays are validated with 2D FEA.
