Electronic Controller
An electronic controller (ESC) manages power distribution, constantly adjusting the current to the windings based on rotor position feedback.
Rotor Rotation
The ESC energizes specific windings in the stator to create a rotating magnetic field that interacts with the permanent magnets, causing the rotor to turn.
Pros
- Higher efficiency
- Longer lifespan
- Reduced heat generation
- Increased power-to-weight ratio
- Improved battery life
- Smoother operation
- Less maintenance required
