As the "core controller" of the UAV power system, the UAV electronic speed controller (ESC) works on the principle of converting the DC power output from the battery into the three-phase AC power required to drive the motor. By real-time adjustment of current and voltage parameters, it precisely controls the motor's speed and torque, directly affecting the UAV's flight stability, power response speed, and energy efficiency. Nanchang Changkong Technology has developed an ESC product matrix covering a wide range of voltage and current levels for different UAV application scenarios.
