Analysis and optimization of a permanent magnet harvesting device

能量收集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。其中要提到的是，热电能量采集器将热量转换为电能。压电能量采集器将机械应变转换成电能。存在振动运动的永磁体结构是用于能量收集的流行来源。永磁结构由于其高能量密度和无线操作而越来越受欢迎。在拟议的研究项目中，MagTech可再生能源公司。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磁分析和优化的磁能收集器设计和开发的分析和数值方法。磁能量收集器是作为一种能量收集器，由永磁体作为其主要部件组成。1）开发高性价比、高扭矩输出装置; 2）研究铝材料的涡流阻尼效应，降低涡流引起的铁损; 3）研究安装永磁体的退磁。在项目实施过程中，一名博士生，一名博士后研究员，一名本科生研究助理和两名顶点项目学生将参与该项目。他们将接受一些关键领域的培训，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.
