Abstract: Overheating of permanent magnet (PM) machines has become a major technical challenge as it gives rise to magnet demagnetization, degradation of insulation materials, and loss of motor efficiency. This paper proposes a state-of-the-art cooling system for an axial flux permanent magnet (AFPM) machine with the focus on its structural optimization. A computational fluid dynamics (CFD) simulation with thermal consideration has been shown to be an efficient approach in the literature and is thus employed in this work. Meanwhile, a simplified numerical approach to the AFPM machine with complex configuration in 3D consisting of conduction, forced convection, and conjugate heat transfer is taken as a case study. Different simplification methods (including configuration and working conditions) and two optimized fans for forced convection cooling are designed and installed on the AFPM machine and compared to a natural convection cooling system. The results show that the proposed approach is effective for analyzing the thermal performance of a complex AFPM machine and strikes a balance between reasonable simplification, accuracy, and computational resource.
This paper deals with 3-D CFD thermal analysis of a permanent magnet motor with cooling fans. The authors designed two optimized fans for forced convection cooling. They have installed them on the axial flux permanent magnet (AFPM) machine for comparison with the nature convection cooling system. The results showed that the simplified numerical approach of the AFPM machine with a complex configuration in three-dimensions (3-D) is effective for analysing the thermal performance of the complex AFPM machine.
