Abstract
The critical speed of eddy current braking is a vital parameter in the design of eddy current braking devices. Currently, most simulations and experiments are used to determine the critical speed, which means a lot of time costs. This paper presents two laws of critical speed variation to help designers more quickly determine the critical speed of a particular eddy current braking device. At first, the structure and the critical speed principle of permanent magnet rotary eddy current brake (PMRECB) are described. Secondly, the finite element analysis is used to verify the accuracy of the two laws. Finally, the validity of the finite element model is confirmed by the eddy current braking test.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
