| Abstract |
The industry is experiencing a gradual shift towards electrification, with various types of equipment replaced by electrical rotating machines. Also, the unit capacity of large machines is gradually increasing to improve the machine's efficiency and reduce operating costs. Modularization is essential to facilitate the assembly of these machines and repairs in case of failure. In this paper, the authors review the basic slot/pole combinations that allow modular winding and propose a 36-slot/10-pole fractional-slot concentrated winding with a single layer. This method could significantly improve the machines' fault-tolerance performance. The authors have conducted a thorough examination of the electrical performances of this proposed winding method, comparing it to a prototype shaft generator to provide a comprehensive analysis. The no-load test result shows the mutual consistency of the finite element analysis, reinforcing the confidence in the validity of this research |
