Novel Partitioned Stator Dual-PM Flux-Switching Permanent Magnet Machine with Mechanically Continuously Flux Adjusting Capability
Abstract
A novel partitioned stator dual-PM Flux-switching permanent magnet (PM) machine with mechanically continuously flux adjusting capability is proposed and analyzed for applications which demand large speed range and high efficiency. This is a novel concept of mechanically adjusted variable-flux (MVF) for flux-switching permanent magnet (FSPM) machines, and it can achieve the same effect as the flux-weakening control in electric vehicles. Two arrays of PMs are inserted into the outer stator and inner stator respectively, and the only one set of winding is placed in the outer stator. The outer stator is fixed while the inner stator is rotatable, and the PM flux could be regulated continuously by adjusting the relative position of inner stator and outer stator. The flux weakening capability and other electromagnetic performances of the proposed machine are investigated by 2D-FEA analysis.
