摘要：

The grating type velocity measuring method shows great promise in getting the velocity of high power and large thrust linear motors. In this paper, the analytical model of velocity measuring sensor is deduced, and verified through experiment. The analytical model of electromagnetic field produced by "8" word rectangular planar spiral coils is obtained from the second order vector potential formulation. The probe coil's inductance value calculated from analytical model and the value measured by bridge are compared. The inductance changes when probe coil is upon a half- space medium plane are deduced, and used to analyze the influence of grating bar material's electromagnetic property. Experiment is designed to verify the validity of the analytical model, and the experiment results match the analytical model very well.
