Comparative Analysis of Disk Type Electrical Machines Designs

Abstract

Modern electrical machines in the aviation industry are used in relatively new and non-standard applications. These new applications place significantly higher demands on electrical machines when it comes to power density and energy efficiency. Thus, electrical machines technologies for the aviation industry are aimed at increasing the power density and energy efficiency of each of the elements of the aircraft propulsion system. Disk type electrical machines with axial flux by permanent magnets are of interest for use in aircraft propulsion system with limited axial dimensions. In this work, numerical simulation of various designs of disk type electrical machines was carried out and the most effective design has been determined to ensure the maximum possible energy characteristics. It has been established that the weight of active parts of the ironless disk type electrical machine with the Halbach array has the smallest weight of active parts in comparison with other disk type electrical machine designs.
