Operating principle and workmanship

The Sunnysky X2220 III engine is a type of brushless motor with an external rotor (Outrunner). The rotating outer body with powerful neodymium magnets creates the high torque needed for sharp maneuvers and rapid climb. The brushless design guarantees high efficiency, no sparking and minimal wear, limited only by the life of the precision bearings.

The manufacturer Sunnysky uses only high-quality materials in this motor. The CNC machined aluminum body is not only durable, but also excellent at dissipating heat, preventing overheating during long-term use. The rotor is carefully balanced, which guarantees smooth running and no vibration even at maximum speed. The third generation motor (III) has improved characteristics and a reinforced design.
