Abstract
This paper presents a design process and a detailed multi-physics analysis of an axial flux permanent magnet synchronous machine for large power direct-drive applications. The machine in this paper is 130kW at 26 rpm with a dual-stator inner-rotor structure. A stator core which is assembled with segmented and pre-wound teeth is first proposed and applied in a large power axial flux PM machines. Through this method, the challenges of manufacturing large diameter AFPM machines can be solved. A novel water-cooling system is embedded in the machine to transfer the heat. In addition, assembling procedure and manufacture process are also proposed. Finally, based on the multi-physics design, a prototype machine is manufactured and tested. The experiment results match well with the finite-element analysis (FEA).
