Analysis and optimization of a permanent magnet harvesting device

能源收集一直是绿色能源技术领域的重要研究课题。文献中报道了将各种能量转化为电能的不同机制。其中值得一提的是，热电集热器将热能转化为电能。压电式能量采集器将机械应变转化为电能。存在振动运动的永磁体结构是一种流行的能量收集来源。永磁体结构由于其较高的能量密度和无线操作而越来越受到人们的欢迎。在拟议的研究项目中，Magtech Renewable Energy Inc.将与滑铁卢大学团队合作进行建模研究，包括使用有限元方法进行分析和数值方法，以对Magtech设计和开发的磁能收集器进行磁场分析和优化。磁力采能器是以永磁体为主要部件的能量采集器，将进行以下方面的研究：1)高性价比、高扭矩输出装置的研制；2)铝材涡流减振和降低涡流铁损的研究；3)安装的永磁体的退磁研究。在项目过程中，将有1名博士生、1名博士后研究员、1名本科生研究助理和2名顶峰项目学生参与。他们将接受多个关键领域的培训，包括磁能收集系统设计、有限元分析和原型制造。

Energy harvesting has been an important research topic in the field of green energy technology. Different mechanisms were reported in the literature for converting a variety of energy into electricity energy. Among them to mention, a thermoelectric energy harvester converts the heat into electrical energy. A piezoelectric energy harvester converts the mechanical strain into electrical energy. Permanent magnet structures in presence of vibrational motion are a popular source for energy harvesting. The permanent magnet structures is being more and more popular due to its higher-energy density, and wireless operation. In the proposed research project, MagTech Renewable Energies Inc. will collaborate with the University of Waterloo team to conduct research for modeling including analytical and numerical approaches using finite element method to perform magnetic analysis and optimization of a magnetic energy harvester designed and developed by MagTech. The magnetic energy harvester is used as an energy harvester consisting of permanent magnets as its major component.Research will be conducted on; 1) Development of a cost-effective and high torque output device, 2) Study on the eddy-current damping effect of aluminum material and reducing the core-loss caused by eddy-current, and 3) Study on the demagnetization of installed permanent magnets.During the course of the project, one PhD student, one Postdoctoral researcher, one undergraduate research assistant, and two capstone project students will be engaged in the project. They will be trained in a number of key areas, including magnetic energy harvesting system design, finite element analysis, and prototype manufacturing.
