The SunnySky X Series X3520 III represents a precision-engineered brushless motor built for the rigorous demands of commercial and heavy-lift drone platforms. Its core design centers on a 35mm stator diameter paired with a 20mm thickness, creating a high-torque foundation capable of spinning large-diameter propellers efficiently on 3S to 4S power systems. The motor’s robust mechanical construction ensures longevity under continuous high-load conditions typical in aerial photography, surveying, and payload delivery operations.
Electrical performance is driven by an optimized magnetic circuit featuring N48UH-grade arc magnets and a precisely controlled 0.2mm air gap, which collectively minimize iron loss and maximize power conversion. Combined with a high copper space factor from manual winding, this design achieves a peak power handling of 1395W. The integrated hollow-carved stator cap and rotor design actively channel airflow to manage operational temperatures, supporting the motor’s high continuous current rating of 83A for 30-second intervals.
