Description This motor is specially designed for BOB57 Cinematic LRFreestyle 6inch BNFThe 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 bearingsCenter slotted N52H curved arc magnetsXING O ring bearing gap protectionCrash resistant 7075 aluminum bellMotor wires protectorDynamically balancedSpecifications Product Name BOB57 2506 6S 1500KVKV 1500KVWeight included wire 38 2gDimension Ï?31 7 19 6mmInterphase Resistance 74 88mΩInput Volts 25 2VPeak Current 33 26AMax Watt 817 5WMounting Holes 16 16 Ï?3mmRotor Specifications UnibellShaft Diameter 5mmShaft Protruding Length 15mmL
