The T-Motor AIR 40A ESC is a 2-6S multi-rotor UAV ESC that the page says is compatible with various flight-control systems and supports a signal frequency of up to 621 Hz. It gives a smooth, linear and precise throttle response.
The specification list gives a maximum RPM of 210,000, a maximum output current of 5A and a voltage regulator of 3.3V, as printed. It has three start modes, a configurable throttle range and a music function with 15 selectable songs using a program card. The page showed it in stock at Rs 3,499 (SKU RS5671).
40A 2-6S ESC: for multi-rotor UAVs.
Signal frequency up to 621 Hz: as listed.
Smooth, linear throttle response: as described.
Three start modes: normal, soft and super-soft.
Music function: with a program card, 15 songs.
Protections: low voltage, overheat and throttle signal loss.
An electronic speed controller (ESC) converts the throttle signal from the flight controller into the three-phase power that a brushless motor needs. It switches battery current through MOSFETs at high speed, so the motor turns at the speed that the pilot or autopilot asks for. The continuous current rating shows how much current the ESC can carry all the time, and the burst rating shows what it can survive for a few seconds.
Match the ESC to the rest of the power system. The battery cell count must fall inside the listed range, the continuous current must be higher than what your motor and propeller draw at full throttle, and the signal protocol (for example PWM, Oneshot, Multishot or DShot) must be supported by your flight controller. An ESC marked OPTO has no built-in BEC, so the receiver and flight controller need power from another source. An ESC with a BEC can supply a regulated voltage, usually 5V, to small electronics.
Install and test carefully. Solder joints must be clean and strong, the motor wires should be kept short and tidy, and the ESC needs airflow because current makes heat. Calibrate the throttle range if the ESC needs it, check the motor direction with the propellers removed, and never connect a battery with the propellers fitted while you are working on the wiring. Use a battery with a cell count and connector that suit the ESC, and check for a heat problem after a short test hover.
