iFlight BOB57 2506 1500KV 6S Brushless Motor for BOB57 Cinematic Long Range Freestyle 6 Inch FPV Racing Drone Description: This motor is specially designed for BOB57 Cinematic LR & Freestyle 6inch BNF The smooth, reliable and powerful motors were upgraded and we achieved an even higher standard in our manufactory as well as better performance than ever before. New center slotted N52H curved arc magnets were introduced to drastically reduce response time of the motor Maybe the biggest bottleneck of our FPV flight controller is the motor due to it's translation delay of it braking and accelerating. This motors offer faster response to translate your PID loop quicker and get that locked-in feeling you were always looking for Due to the high quality materials used and the durable joint of bell and shaft, we were able to reduce the magnet air gap and stator lamination to a minimum. The smaller the air gap is, the lower that reluctance and the higher the magnetic flux (which is the magnetic analog of current) causing more efficiency and higher power Features: 5mm titanium alloy shaft, our strongest prop shaft ever Smooth and long-lasting NSK 10x4x4 bearings Center slotted N52H curved arc magnets XING O-ring bearing gap protection Crash resistant 7075 aluminum bell Motor wires protector Dynamically balanced Specifications:Product Name: BOB57 2506 6S 1500KV KV: 1500KV Weight(included wire): 38.2g Dimension: φ31.7*19.6mm Interphase Resistance: 74.88mΩ Input Volts: 25.2V Peak Current: 33.26A Max Watt: 817.5W Mounting Holes: 16*16 φ3mm Rotor Specifications: Unibell Shaft Diameter: 5mm Shaft Protruding Length: 15mm Lead: 160mm/20AWG Magnet: N52H Curved Configuration: 12N14P Bearing Type: NSK Bearing Specification: φ10*φ4*4 Winding: Single Strand copper winding Package Includes: 1 x BOB57 2506 1500KV 6S FPV Motor 1 x M5 Flanged Nylon Insert Lock Nut 4 x M3*8mm screws OR 4 x BOB57 2506 1500KV 6S FPV Motor 4 x M5 Flanged Nylon Insert Lock Nut 16 x M3*8mm screws
