| Abstract: | This project aimed to identify the characteristics of an unknown PMDC motor through automated measurements. Using a current sensor, encoder, and load cell, the measurements were realized. Despite time constraints, we successfully analyzed velocity and current step responses, determining their corresponding time constants and armature resistance. Although the motor constant, inertia, and friction could not be determined, the inductance was inferred using the electrical time constant and resistance. Issues in the RPM vs torque measurements were traced to mechanical setup instabilities, notably an unbalanced axle and misalignment, causing irregular torque data. Validation through RPM vs time and torque vs motor angle plots confirmed these mechanical issues. Our findings show the motor's resistance and inductance values to be higher than expected, attributed to sensor noise and measurement limitations. The final results offer a comprehensive understanding of the motor's electrical parameters, laying the groundwork for future improvements in mechanical stability and measurement accuracy. |
