More Information
Summary:A novel partitioned primary linear switched flux permanent-magnet machine (LSFPMM) is presented. Its primary is divided into two separate parts: one is the armature containing iron core and windings, and the other is magnetic poles containing PMs and iron core. For the optimal design objective of maximum thrust force and minimum thrust ripple, the novel partitioned primary LSFPMM with 9 primary/10 secondary poles is optimized. The electromagnetic performance of this optimized partitioned primary LSFPMM has been analyzed and compared with that of original one. The corresponding prototype of optimal design is manufactured and possible machining errors are discussed. Finally, the measurement is carried out, which verifies the predicted results. The research shows this novel structure has high force performance and is suitable to machine tools, conveyers and punching machine.
