Device Modeling of Stepping Motor using SPICE
This document discusses stepping motor device modeling. It describes frequency models including 3-element, 5-element, and ladder models. It also discusses adding internal voltage dependency to frequency models. Graphs and circuit diagrams are provided to show impedance characteristics and example motor drive circuits. Simulation results examine effects of clock speed on current rise time and develop a function to model back EMF voltage based on motor speed. The goal is to accurately model stepping motor behavior for integration into system simulations.
