High Torque 40 Pairs Poles 8108 44.4V 400W Outrunner Brushless DC Motor with 12s ESC for Multirotors, Quadcopter and Fixed Wing Drones

Characteristics

  1. 40 pairs of poles hi-torque motor design Precision engineered for highest strength conversion Precision balanced rotor, smoothness for greatest trustworthiness and greatest RPM
  2. A number of security functions: Low voltage minimize-off security, above-warmth defense, throttle signal reduction safety
  3. Prolonged stable overall performance: No mistake time lasts extended for 2700 hours at 24V voltage and 60A present doing work circumstances.
  4. Fulfill Countrywide Navy standard, EMC, FCC,CE and so on.
  5. Appropriate for industrial and specialised drones( Multi-rotor, set wings drones)
  6. Shaft: Higher hardness, lengthy lifespan( Special stainless metal)
  7. Housing: 7075 collection aerial professional large hardness aluminum alloy, a lot more high-priced than the 6000 sequence with lower alloy hardness and the screw  straightforward to loose.
  8. Magnet: special permanent magnet with good functionality and  special warmth resistance.
  9. Coil: Higher purity copper windings maximizes effectiveness CZPTed from Japan with good overall performance, high warmth resistance Undertake vertical varnish technology to make the wire thickness even
  10. Bering: CZPTed(Not-refurbished)
  11. Iron core: CZPTed, exclusive silicon metal sheet.
