DC motors convert electrical energy to mechanical rotation through the interaction of magnetic fields and current-carrying conductors. This simulation models the motor's electrical circuit and mechanical dynamics simultaneously, showing how armature current, back-EMF, and torque evolve during start-up and under varying loads. The torque-speed curve is central to selecting the right motor for any application.
