40A Brushless ESC

40A Esc Brushless Motor Speed Control Board

Drone Airplane Rc Fpv Toys Quadcopter Helicopter Brushless

     This is an electronic speed controller (ESC) for brushless (3-phase) motors that delivers 40A continuous and 55A short-term (max 10s) current. It works with 2S - 4S LiPo or NiMH batteries and sets the motor speed according to the PWM throttle signal coming from the RC receiver or the flight controller. The on-board linear BEC supplies 5V 3A to the receiver and servos; no separate receiver battery is needed.

     The board measures 68mm x 25mm x 8mm and weighs approx. 30gr; it is enclosed in a black heat-shrink sleeve. At one end there are the red / black battery input wires and a 3-wire signal cable (JR / Futaba type connector), at the other end three 16AWG black phase wires going to the motor. The wire ends come bare (tinned); solder connectors that match your battery and motor.

     It has low voltage cut-off, over-temperature, start-up and throttle signal loss protection. The throttle range can be calibrated and settings such as timing can be programmed for different brushless motors.

Key features:

     40A continuous, 55A burst current: Drives medium size drone, RC airplane and helicopter motors at 40A continuous; gives 55A for up to 10s during take-off and sudden manoeuvres.

     Built-in 5V 3A BEC: The linear BEC powers the receiver and up to 4 standard servos; no need to carry a separate receiver battery.

     2S - 4S LiPo and NiMH batteries: Works with 7.4V - 14.8V LiPo packs and NiMH batteries; low voltage cut-off protects the battery from over-discharge.

     Protections: Over-temperature, throttle signal loss and start-up protection (the motor does not start unless the throttle is at zero) prevent accidents and a burnt board.

     Programmable: Throttle calibration is supported and timing can be changed for different brushless motors; also compatible with disk type motors.

Usage information:

• Connect the 3 motor phase wires to the 3 motor wires in any order; if the motor turns the wrong way, swap any two phase wires. Connect the red wire to battery positive and the black wire to battery negative; reverse connection burns the board.
• Plug the signal cable into the throttle channel of the receiver (or the motor output of the flight controller). Calibrate the throttle on first use: connect the battery with the throttle at full, after the confirmation beeps move the throttle to the bottom.
• Mount the board where propeller wash or air flow passes over it; near 40A cooling is required.

Applications:

•  Drone and quadcopter motors
•  Hexacopters and other multicopters
•  Radio controlled (RC) airplanes and gliders
•  RC helicopter main rotor motor
•  FPV flying models
•  RC boats and speed boats
•  Model cars and tracked vehicles
•  Brushless fan, propeller and thrust test rigs
•  Robots and vehicles with brushless motors
   

Precautions:

•  This board is for brushless (3-wire) motors only; it does not drive brushed (2-wire) DC motors.
•  This is an airplane / drone type ESC; it has no reverse function (turning the motor backwards with the throttle). In model cars and boats the motor turns in one direction only; there is no water cooling for boats, place the board where it gets air flow.
•  The current drawn by the motor and propeller must not exceed 40A continuous; 55A is only for max 10s. If the motor current is close to the ESC rating, choose a higher current ESC.
•  Do not connect a battery higher than 4S (14.8V). The linear BEC heats up at high battery voltage; do not power many servos from a 4S battery.
•  Remove the propeller from the motor during setup and calibration.
