| Two-phase hybrid linear stepping motor(LSMs), as a kind of ideal high-tech linear drivers, has been applied widely in the linear servo systems drived directly with high resolution. Considering SLPMU-025A produced by Japan SHINKO motor company Ltd.as our study project, this thesis presents a study on two-phase hybrid LSM, the study objects and some conclusions presented in the thesis are: (l)The 3D model of SLPMU-025A is formed by software Maxwell 3D. Then, the 3D magnetic field of the motor is analyzed by FEM(fenite element method)analysis. Here, the analysis of the magnetic field is in focus on the region of tooth-layer. (2)The static thrust-displacement characteristics is calculated by post-processing function of software Maxwell3D. The experiment results show a good agreement with the calculated values. (3)Based on the mathematical model described by Simulink in software MATLAB for dynamic simulation of the motor , some dynamic characteristics are obtained and the experiment results validate the method described here.
