ESC Speed controller

An Electronic Speed Controller (ESC) is a purpose-built device designed for controlling the speed of an electric motor. Using a specialised combination of hardware and firmware, ESCs drive motors to a commanded speed. They maintain motor speed under various circumstances, such as the dynamic load of a propeller.

The ESC (Electronic Speed ​​Controller) is a key component of FPV (First Person View) drones, which is responsible for controlling the rotation speed of the motors. It receives signals from the flight controller and regulates the power supplied to the engines, providing stability and control during flight.

Main functions of ESC for FPV:

Motor speed control – ESC controls the rotation of each motor, allowing the drone to quickly change direction, altitude or speed.

Overheat Protection – Modern speed controllers have built-in protection mechanisms to prevent components from overheating or overloading.

Braking (Active Braking) - this function allows the motor to quickly stop or change direction, which is especially important for FPV flights, where high maneuverability is required.

Compatibility with different types of motors – ESCs can work with different types of brushless motors, making them versatile for different models of drones.

Telemetry – Some ESC models can transmit engine and battery status data to the control panel, allowing the pilot to monitor real-time readings.

Advantages of using ESC in FPV drones:

High control accuracy.

Improved stability during flight.

Optimization of energy consumption to extend the duration of the flight.
