Abstract :
A high frequency (HF) electrical model of a DC motor armature is derived from its geometric and physical properties. This model includes the armature windings´ properties as well as inductive and capacitive couplings between windings, armature, axis, and commutator surfaces. It provides sufficient detail to simulate the armature´s complex impedance up to a frequency of approximately 1 GHz, provides expressions to calculate the model elements from construction parameters and visualizes their influence on the impedance.
