Analysis of a permanent magnet DC motor explosion-removal robot system based on thermal energy optimization control

Based on the quasi-limit theory’s design principle, the paper analyzes the steady-state and transient temperature rise laws of the motor with different overload currents from the heat transfer perspective of permanent magnet DC motors. The paper takes the EOD robot as an example. Using this law, the current overload, and temperature rise of the robot wheel motor is analyzed. The study found that the continuous-duty motor (S1) selected is conservative and has an extensive design margin.
