Static and dynamic carrying capacity are discussed, as well as dynamic relative placement characteristic of axial force and relat ive placement bet ween outer and inner magnetic sleeves. The condition that magnetic driver works steadily is generalized. The conclusion shows that w hen t he magnet ic characteristics and dimensions of inner and outer magnet ic sleeves are decided, the characteristic between axis force and the relative placement of inner and outer magnetic sleeves is irrespective with slide block st roke, working frequency and the opening of flow regulating valve, so it provides a forceful evidence for simplifying the calculation of magnetic force.
