Overview
T-Motor AX525-A is a fixed-wing brushless motor in the AX Series, a power system specifically engineered for fixed-wing cruise UAVs. It is designed for pusher configurations with rear shaft output for internally mounted installations and front shaft output for externally mounted installations to fit different airframe layouts.
For pusher applications, the end caps use tilted centrifugal cooling fins aligned with the rotation direction to improve heat dissipation efficiency by 5%. An integrated collet-type prop hub supports quick installation of folding propellers.
Key Features
- AX Series brushless motor platform for fixed-wing cruise UAVs
- High mounting versatility: rear shaft output (internal mounting) and front shaft output (external mounting)
- Enhanced cooling efficiency: tilted centrifugal cooling fins, +5% heat dissipation efficiency
- Quick installation: integrated collet-type prop hub for folding propellers
