SUMMARY
The discussion centers on calculating the rotational speed in a DC machine, specifically addressing the importance of determining the torque constant (Kt) as it varies with the excitation voltage (Vexc). The participant initially approached the problem incorrectly but corrected their method by first calculating Kt and then using this value to find the new rotational speed while maintaining constant torque. This highlights the critical relationship between excitation voltage and torque in DC machines.
