Observe Rotor Integration

What happens here

Following the stator demonstration, the presenter showcases a brake drum that has been specially modified to integrate the rotor. This rotor, which consists of strategically placed magnets, is securely fitted into the inner circumference of the brake drum. As the trailer wheel turns, the brake drum and its integrated rotor spin around the stationary stator. This dynamic interaction between the rotating magnetic field of the rotor and the coils of the stator is the fundamental mechanism that generates electrical current, thereby charging the trailer's battery.

Goal: Understand the placement and conceptual function of the rotor within the brake drum.
