Abstract :
A novel permanent magnet (PM) flux concentration-type linear oscillatory actuator (LOA) for a compressor is proposed in this paper. The proposed LOA has an embedded PM structure and the structure is effective in magnet flux concentration. The flux concentration has a positive influence on the flux linkage, cogging force, and electromotive force. The superiority of the proposed LOA has been confirmed by comparing the performances between the proposed and conventional LOA.
