The Hobbywing XRotor 40A is made for DIY multicopter drones, giving great performance and stability according to the page. It features optimised firmware for disc motors and a twisted throttle signal wire to reduce interference during flight.
The specification table gives a model of XRotor 40A, a 2-6S lithium input, 40A continuous current, 60A instantaneous current for 10 seconds, a size of 68 x 25 x 8.7 mm, a weight of 26 g, a 3.5 mm banana plug and a throttle signal rate up to 621 Hz. The page also mentions customisable increment angles. It showed 49 units at Rs 2,420 (SKU TIFQC0105).
40A continuous, 60A instantaneous: burst for 10 seconds.
2-6S lithium input: as listed.
Optimised firmware for disc motors: as described.
Twisted throttle signal wire: reduces interference.
Throttle signal up to 621 Hz: as listed.
3.5 mm banana plug: included.
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.
