Abstract
This paper details the modeling of the armature current in a permanent magnet direct current machine based on its frequency response characteristics. Additionally, the dynamic behavior model of the machine is derived using the conventional methodology, which encompasses three distinct tests: no-load, blocked rotor, and deceleration. The empirical findings corroborate the equivalency of the two models. The experimental approach of transient and frequency response analysis proves to be a successful experience towards the implementation of the new National Curricular Guidelines for Engineering.
