Product overview
The YRDRONE JT6008 KV160/KV320 is a brushless propulsion motor for heavy-lift and long-endurance multirotor UAVs, offered in 160 KV and 320 KV versions. Its construction combines a 24N28P stator with a 60 mm outer-diameter, 8 mm-high core using Kawasaki 20JNEH1200 material. The shaft uses SUS420J2 martensitic stainless steel, while N48SH NdFeB magnets and a precision CNC housing complete the architecture. Both versions weigh 157+/-10 g and measure 67.7+/-0.15 mm in diameter. Axial length differs: 21.1+/-0.3 mm for KV160 and 23.1+/-0.5 mm for KV320.
Integration recommendations specify 21–22 inch propellers, 14S LiPo cells and a 14S/80 A ESC for both versions. The motor options have different electrical ratings: KV160 permits 23.8 A and 1142 W continuously at 48 V, while KV320 permits 40 A and 960 W continuously at 24 V. Maximum ratings are 40 A/1920 W and 60 A/1440 W respectively, each limited to 15 seconds. Magnet operating temperature is limited to 150°C, with 120°C recommended as the maximum. Thrust varies with propeller, voltage and test conditions.
