Finite Element Analysis of Double-Side Stator Permanent MagnetLinear Motor Drive Punch

Stamping punch directly driven by permanent magnet linear motor (PMLM) exhibits many merits, and the stator-PMLM (SPMLM) is an attractive motor type for its robust salient-pole secondary mover. A novel double-side SPMLM drive punch is presented, the SPMLM topology and the punch structure are designed. Finite element analysis (FEA) with response surface methodology (RSM) is implemented to determine the machine dimension parameters and optimize the output force. Besides, thermal performance is analyzed in the coupling electromagnetic-thermal FEA.
