Modeling and Simulation of Micro Step Drive for a Hybrid Stepper Motor

The simplified dynamic mathematical model of hybrid stepper motor was studied in this research. The aim was to simplify the study and to concentrate on certain topic of this subject. The mathematical model which describes their mechanical and electrical dynamic behavior of the mentioned motor was done. Whereas, the mechanical model can be derived by Newton law, and electrical model can be derived by Kirchhoff law depending on the electrical equivalent circuit to each phase.
