固定翼应用.jpg

This series features high-performance long-stator brushless motors, including four mainstream models: KV200, KV220, KV245, and KV270, specifically designed for RC aircraft, drones, and electric power systems.  

All models share a compact housing dimension of Φ81.4×57.9mm, featuring a 24N22P slot-pole configuration with 100mm high-temperature-resistant enamel wire, combined with dual 10mm IN/OUT shaft diameters to ensure both structural strength and transmission stability. The total weight, including the wire, is only 550–565g, achieving an optimal balance between lightweight design and high power density.
