Abstract

Analytical approaches could be very useful in the design and analysis of electromagnetic devices. This paper is concerned with the design and analysis of an axial-flux wound-excitation eddy-current brake, for which a subdomain-based analytical approach is developed, whereby performance characteristics and design considerations of the device are evaluated. The practical constraints of the proposed structure are discussed and 3-D finite-element analysis (FEA) is employed in the analyses as well as validation of the implemented model. Moreover, a parametric analysis is performed, which provides valuable information regarding the design of the device. In addition, the extracted closed-form expressions for the brake characteristics can be used in the design of the associated control systems. Finally, a prototype has been manufactured whose results agree well with those discussions issued from FEA as well as the proposed model.
