Abstract
To address the issue of significant fluctuations in radial electromagnetic forces in variable-leakage-flux reverse-salient-pole permanent magnet synchronous motors (VLF-RSPMs), which make stable operation at high speeds difficult, this paper combines an analysis of existing VLF-RSPMs with a novel optimization method to propose a multi-objective hierarchical optimization design method for VLF-RSPMs, which incorporates vibration and noise suppression. First, the paper analyzes the radial electromagnetic force model, natural frequencies, and electromagnetic vibration model of the VLF-RSPM. Second, based on the optimization objective of vibration and noise suppression, parameters with high sensitivity are optimized first through sensitivity analysis. Subsequently, the modal characteristics, radial electromagnetic forces, noise, and stress of the optimized VLF-RSPM are analyzed in detail. Finally, an experimental VLF-RSPM prototype and a test platform for measuring radial electromagnetic force fluctuations are designed. The results demonstrate that the multi-objective hierarchical optimization design method ensures the operational reliability of the optimized VLF-RSPM, enabling it to meet the requirements for high-speed operation.
