Abstract

By combining the theory of mechanical flux-adjusting with the advantages of an interior permanent magnet synchronous machine (PMSM), a new type of auto-rotary PMs mechanical flux-varying PM machine (ARPMMFVPMM) is creatively proposed in this paper. The operation principle and mechanical flux-adjusting mechanism were deeply investigated. The relationship between deformation of spring and auto-rotary angle of gear against speed was obtained by Automatic Dynamic Analysis of Mechanical System (ADAMS). Meanwhile, the electromagnetic characteristics of the machine were numerically analyzed by Finite Element Analysis (FEA). The simulation results show that the auto-rotary of cylindrical PMs is realized by the centrifugal force of mechanical device, and the range of speed regulation is expanded by adjusting the magnetic field distribution.
