T-MOTOR AIR 40A 2-6S Multi-Rotor UAV Drone ESC

Where Lightness Meets High Efficiency: The AIR Series

The T-Motor AIR 40A is an electronic speed controller specifically optimized for professional aerial photography and industrial inspection drones. Supporting a wide voltage range from 2S to 6S (25.2V), this ESC continues T-Motor’s legendary tradition of "smooth throttle response." Its internal architecture, focused on energy efficiency, maximizes battery life, while the low internal resistance MOSFET structure minimizes heat generation.

AIR 40A ESC Key Features

• Optimized Flight Algorithm: The software specifically developed for multi-rotors automatically adjusts motor timing. This ensures perfect harmony between the motor and the ESC, eliminating the risk of synchronization loss.

   

• Ultra-Low Noise and EMI: Thanks to advanced circuit design, electrical noise (interference) is kept to a minimum. This allows sensitive navigation hardware like GPS and telemetry to operate much more stably.

• Fast Throttle Response: Supporting a signal refresh rate of up to 621Hz, it instantly transmits commands from the autopilot to the motor, enabling the drone to hover much more stably.

• Compact and Heat Dissipating Design: Its slim profile allows for easy installation inside or underneath carbon fiber drone arms. The open-channel design enhances cooling by utilizing airflow during flight.

   

• Easy Plug-and-Play: Factory calibrated to work directly with most professional brushless motors, without the need for complex programming processes.

Usage Recommendation:

For maximum efficiency, it is recommended to pair with T-Motor AIR 2216, AIR 3510, AIR 3520 or MN Series motors. Since this ESC has an "OPTO" design, an external voltage regulator (BEC) must be used to power the flight controller (FC).
