Review of the Application of Composite Materials in Electrical Machines

Abstract

This paper describes typical composite materials that are already used or can be used in the components of electrical machines. In the presented review of composite materials, their main advantages and limitations are identified. Specific examples of the use of composite materials in electrical machines are given. This article also studies the feasibility and the fundamental possibility of creating an electrical machine for microturbines entirely composed of composite materials. For this purpose, electromagnetic and thermal analyses using finite element methods have been performed. According to the results of these analyses, a comparison of the characteristics of an electrical machine is made consisting of traditional materials and electrical machines partly or fully consisting of composite materials. As a result, proposals are formed on the prospects for the use of composite materials in electrical machines. The main contribution of this article in the field of design and creation of electrical machines is the synthesis of data on composite materials used in electrical machines, as well as the demonstration of the prospects of an electrical machine entirely composed of composite materials.
