SunnySky XS High Power X3515S Brushless Motors

Description

Powerful Multirotor Motors

The new patented XS design combines a sleek, industrial look with superior functionality. Its semi-enclosed structure effectively prevents sand and debris from entering the motor while also enhancing ventilation and heat dissipation.

Advanced Large-Diameter EZO Bearings

Equipped with premium Japanese EZO bearings with large diameters, the XS motors ensure stable, quiet operation and long-lasting performance.

Hand-Wound Coils

Each motor features precision hand-wound coils, ensuring low internal resistance, high efficiency, and up to a 90% coil space factor. This results in increased maximum continuous power for every XS motor.

Sunnysky's Ultimate Manufacturing Technology

Built with Sunnysky’s advanced manufacturing and assembly techniques, XS motors are crafted with precision, featuring tight tolerances and minimal shaft and radial runouts. This ensures smooth and reliable operation in the air.
