T-Motor Antigravity MN2806 EVO 650KV Motor

The T-Motor Antigravity MN2806 EVO 650KV is the updated MN2806 for light, long-endurance multirotors on 4S, turning 12-13-inch props for aerial photography, mapping and surveillance. T-Motor quotes a 16% rise in maximum thrust over the original MN2806.

Key features

• Arc-shaped magnets fitted tight to the steel ring narrow the air gap for more even flux and less leakage
• 1389 g maximum thrust on a P13x4.4 prop at full throttle
• Efficiency improved by over 0.3 g/W at comparable thrust levels above 400 g
• Copper winding rated to 220 °C, magnets to 150 °C and stator coating to 180 °C, for reliability under heavy load and heat
• Twin imported 694ZZ bearings and a 4 mm shaft, all at 45 g including leads

Specifications

• KV: 650
• Rated voltage: 4S LiPo
• Configuration: 12N14P
• Dimensions: 34 x 26 mm (diameter x height)
• Shaft: 4 mm
• Weight: 45 g including leads
• Internal resistance: 201 mΩ
• Idle current: 0.45 A at 10 V
• Peak current (180 s): 16 A
• Max power (180 s): 160 W
• Max thrust: 1389 g (P13x4.4, full throttle)
• Recommended props: P12x4 / P13x4.4
• Recommended ESC: T-Motor AIR 40A 6S
