How to choose an ESC for FPV drones: key parameters
FPV drones are becoming increasingly powerful, faster, and more technologically advanced. But even the most sophisticated motor will not show its full potential without a reliable speed controller (ESC). The ESC is responsible for controlling the speed, stability, and response to the pilot's commands. In this article, we will discuss what to look for when choosing an ESC for FPV drones.
1. Current and power reserve.
The main characteristic of an ESC is its maximum current. If the motor consumes 35A, the controller must have a reserve of at least +20–30%. That is, an ESC rated at 45–50A would be suitable for such a motor. *The rule is simple:* it is better to have a reserve than to operate at the limit of your capabilities.
2. PWM frequency and protocol.
Modern FPV drones use high-speed protocols (DShot600, DShot1200) that provide instant response. Therefore, it is worth choosing an ESC that supports: * *digital protocols* (DShot, ProShot); * *high refresh rate* (up to 96 kHz). This is especially important for racing and freestyle FPV drones.
3. Heat dissipation.
The ESC operates with high current, so overheating is its main enemy. Important: * high-quality MOSFETs with low resistance; * well-thought-out component layout; * short-circuit protection; * additional coating against moisture and dust. Translated with DeepL.com (free version)
