Overview

The T-Motor MN505-S KV320 is an IP45 Navigator Type UAV motor designed for multirotor, VTOL, and fixed-wing power systems where dust/water resistance and stable operation are required. The Navigator series is positioned for general UAV uses including aerial photography, with applications such as cargo drones, tethered platforms, mapping, and inspection.

Key Features

  • IP45 protection concept: waterproof, dust-resistant, and anti-corrosion design.
  • Centrifugal fan cooling (bell cap): active cooling design; heat dissipation performance stated as 10% better than ordinary motors.
  • High-temperature resistance: manual winding with special varnished wires; high-temperature resistant magnets; anti-high temperature and anti-overload positioning.
  • Foreign object protection note: grid-shaped bell cap helps keep the motor away from >1 mm foreign objects, including when mounted upside down.
  • Locking method: T-shape shaft secured with a circlip and a screw for “Double Security” under high RPM.
  • Structure for lifespan/impact resistance: uses a 6 mm steel shaft and a 15 mm bearing.
  • Performance optimization: anti-high temperature curved magnets; motor performance stated as improved by 5%+.
  • Mounting note: when mounting the motor, ensure the thread inside the motor is ≤ 5 mm.
