What does an ESC do?
The ESC (Electronic Speed Controller) is the brain of the electric propulsion system. It regulates the current sent to the motor phases to achieve the required speed and torque. It also includes key protection features such as overcurrent, undervoltage, and overtemperature safeguards to prevent damage to the motor and power electronics.
How is the ESC controlled?
The ESC can be controlled by a flight controller, an autopilot, or directly by a transmitter or throttle signal. The most common control interfaces are PWM, CAN, and UART. PWM is simple and widely supported, while CAN and UART enable two-way communication for telemetry, configuration, and advanced diagnostics.
What happens if the ESC overheats?
Most ESCs monitor temperature via internal sensors. If protection is enabled, the ESC will reduce power or shut down. Without thermal protection, overheating can damage MOSFETs or capacitors and permanently destroy the controller.
How to prevent ESC overheating?
Provide adequate airflow or liquid cooling, depending on the ESC design. Avoid overloading the motor, since excessive current directly increases ESC temperature. Ensure correct propeller size or load and verify that wiring and connectors can handle the rated current.
What maintenance does an ESC require?
ESCs are maintenance-free. Keep them clean and dry. Use compressed air to remove dust, and check connectors periodically for corrosion or loose pins. Always make sure the ESC firmware is up to date.
