A new, high quality offering from Flipsky, their new battle-hardened 6384 motor is made in-house. With design feedback directly from highly experienced members of the community, flipsky has been able to manufacture a high-quality motor with design features that make it a cut above the rest. 


  • KV: 140
  • Max Power: 4000Watts
  • Max Current: 95 Amps
  • Max Volts: 13S
  • Max Torque: 8Nm
  • Motor Resistance: 0.05Ohm
  • 14 Poles (7 Pole pairs)
  • Net weight: 1100g
  • Shaft size : 10 -> 8mm Stepped (Uses 8mm bore pulleys)

Key Features:

  • The use of a stepped shaft means the motor shaft won't bend during extreme use, but still supports 8mm pulleys
  • A generous amount of epoxy on the magnets reduces the chances of magnet failure (loose or shattered) tremendously. 
  • A larger stator than other 6384s means the motor can take a higher peak and continuous amperage. On average, this motor detects at 7 amps higher than other high-quality 6384s. 
  • Completely epoxied hall sensors reduce the chance of failure. The hall sensors are also physically embedded into the stator, giving more accurate and consistent readings 
  • Curved magnets give an exceptionally quiet operation in FOC
