Abstract :
This paper presents the design and steady state analysis method of an air core-type permanent magnet (PM) linear brushless motor based on the equivalent magnetizing current (EMC) method. The phenomena of air core-type motors by the variety of foil shape under constant magnetomotive force (MMF) has been analyzed and the analysis process is applied to the design and static state analysis considering commutation thrust ripple. The validity of the proposed technique is confirmed with 2-D finite element (FE) analysis and experimental results
