高速永磁同步电机在多物理场和变流器约束下的设计
Design of High-Speed PMSM Considering Multi-Physics Fields and Power Converter Constraints
摘要
Abstract
Multi-physics fields inside high-speed electrical machines are strongly coupled and may even conflict with each other. Therefore, design of the high-speed machines is extremely constrained by these fields. Moreover, power converters have limited current and voltage, by which the machine design is also constrained. All these constraints become further significant if the machines are of high power. Therefore, it is challenging to achieve a feasible solution of machine design. As a study case, design and optimization of a 350kW and 13.5kr/min interior permanent magnet synchronous motor (PMSM) is presented in this paper. Principal of matching the permanent magnet flux linkage with the winding inductances for various operation conditions is investigated, so that both the voltage and current limits of the power converter can be satisfied. Then, related design aspects are addressed, especially, the rotor configuration considering the electromagnetic performance, mechanical stress and rotor dynamics is studied with finite element methods (FEM), and the thermal behavior is studied with computational fluid dynamics (CFD), demonstrating the comprehensive procedure of multi-physics design.关键词
