Analysis and Experimental Investigation on Flux-Adjusting Characteristic for a Mechanical Flux-Adjusting Axial PM Synchronous Machine
摘要
Abstract
To flexibly adjust the magnetic field of permanent magnet (PM) electrical machine, a novel mechanical device applied in an axial PM synchronous machine is proposed in this paper. The operation principle and mechanical flux-adjusting mechanism were deeply investigated, and the relationship between the deformation of spring and stagger angle of rotors with the speed variation was obtained by virtual prototype technology. The magnetic vector distribution, flux linkage, induced EMF and flux density in air gap were calculated by finite element analysis (FEA). The simulation results show that the stagger angle between the two rotors can be effectively adjusted by the centrifugal force of the mechanical device, and the speed regulation range can be expanded by adjusting the magnetic field distribution. Furthermore, some experiments are performed to validate the theory and simulation results.关键词
