An Electronic Speed Controller that acts as the "brain," switching current to the stator windings in a specific sequence to keep the rotor spinning . 🕹️ Control Methods
Control is achieved by monitoring the rotor's position and energizing the correct stator phase to create a magnetic field that "pulls" the rotor along . 1. Sensored Control
Uses physical sensors (typically ) inside the motor to report the rotor's exact position to the controller . Pros: Reliable startup and smooth low-speed performance .
Extra wiring and potential sensor failure in harsh environments. 2. Sensorless Control
