long-range ESC for drone

Features of Long - range ESCs

• High - efficiency conversion: They adopt advanced power conversion technologies like FOC (Field - Oriented Control) algorithm, which can improve the efficiency of power conversion from the battery to the motor, reducing energy loss and thus prolonging the drone's flight time2.
• High - current handling capacity: They are capable of handling high - current outputs to meet the power demands of the drone's motors, especially for large - scale or high - performance drones that require more power. For example, the DJI E7000's 12100 FOC ESC can endure a continuous current of up to 100A, providing strong power support for the drone2.
• Good heat dissipation performance: They are equipped with excellent heat dissipation designs to ensure the stability of the ESC during high - power operation. For instance, the 12100 FOC ESC of DJI E7000 adopts an advanced double - sided heat dissipation solution for its power MOS, which can effectively dissipate heat and maintain a low - temperature operating state2.

Parameter Selection Considerations

• Voltage range: It should match the voltage of the drone's battery. Common lithium - polymer battery voltages include 2S (7.4V), 3S (11.1V), 4S (14.8V), etc. The ESC must be able to handle the maximum and minimum voltages of the battery to ensure normal operation.
• Current capacity: It needs to be selected according to the power and current requirements of the drone's motors. Usually, the continuous current rating of the ESC should be greater than the maximum current drawn by the motors during normal flight. A general rule of thumb is to choose an ESC with a current capacity 20% - 50% higher than the expected maximum current of the motors.
• Motor compatibility: It should be compatible with the type and model of the drone's motors, whether they are brushless or brushed motors. Brushless ESCs are designed specifically for brushless motors, which are widely used in drones due to their high efficiency, durability, and low maintenance requirements3.

Recommendations for Long - range ESCs

• DJI E7000 12100 FOC ESC2: It is part of the E7000 multi - rotor power system and is suitable for large - scale professional drones. It has a high - current handling capacity, excellent heat dissipation performance, and uses the FOC algorithm to provide precise motor control, enabling the drone to have a longer flight range.
• MAD AMPX 40A Pro (2 - 6S) ESC1: It is suitable for professional - grade 550 / 650 - class quadcopters and multi - rotor drones. It has good compatibility and can handle a certain range of battery voltages, which helps to improve the flight range of the drone.
• MAD AMPX 30A 2 - 6S w / o BEC ESC: It is designed for long - range mapping, aerial photography, and video - shooting drones. It has new core software that improves throttle response and has high - intelligent and adaptive default settings, which can meet a variety of application scenarios and is conducive to extending the flight range.
