T-Motor Navigator MN505-S Waterproof Motor 320KV/380KV

The T-Motor Navigator MN505-S is a waterproof brushless motor for professional multirotors used in aerial photography, surveillance and mapping. It comes in 320KV and 380KV, both rated for 6S LiPo, and takes T-Motor fixed or folding carbon-fibre props: 20–22 inch on the 320KV, 17–18 inch on the 380KV.

Key features

• IP45 enclosed build: resists dust and water ingress, with an anti-rust stator treatment and corrosion protection.

• Centrifugal cooling fan: draws air through the motor to shed heat under sustained load.

• High-temperature windings: 220°C-rated copper wire guards against burn-out from a trapped propeller or overload.

• Reinforced shaft: the internal T-shaped shaft is secured with a clip and screw so the rotor cannot work loose.

• 24N28P configuration running on 696ZZ bearings.
