This paper presents an analysis conducted on direct current (DC) electric motors used in an omnidirectional mobile platform, with a focus on the commutation signal as a primary indicator of their dynamic behavior and functional condition. Omnidirectional platforms provide significant advantages in mobile robotics applications due to their ability to move in any direction without requiring a change in orientation, a capability made possible by the use of four individually controlled DC motors. The study emphasizes the commutation signal as a diagnostic tool for evaluating motor performance, as it directly reflects the interaction between the motor's mechanical and electrical components. The analysis aims to identify key variations in current, partial short circuits, and non-uniformity in the commutation process between the brushes and the commutator segments. Furthermore, the behavior of multiple motors mounted on the same platform is compared in order to assess operational uniformity and its influence on the platform’s omnidirectional motion.
