In order to obtain high performance of a novel linear oscillatory motor with two separated stators which used for directly driven compressor. The expression of power factor and efficiency were also derived based on this mathematical model. In combination with simulated analysis and vector model, the relationships between operating frequency, gas force load and the performance indexes such as power factor and efficiency were investigated in the actual working conditions. On this base, the most optimum operating frequency was further studied in detail. The predicted analysis was validated by corresponding experimental results. Experimental results show the mechanical resonant frequency and frequency point of highest power factor are changed along with the gas force load, and maximum efficiency and high power factor are obtained when the operating frequency reached mechanical resonant frequency．
