Details

T-Motor AT1040 fixed wing motor uses a removable propeller hub and supports real-time speed monitoring with a magnetic encoder system.

The AT1040 motor uses a 110.6 × 109.8 mm body, 24N28P configuration, and a 15 mm/12 mm shaft design to help plan mounting and drivetrain fitment.

T-Motor AT1040 specs list 90KV, 24S rated voltage, 6000W max continuous power, and a detailed thrust test report across throttle settings.

The T-Motor AT1040 KV90 package includes the motor along with a parts bag of mounting screws and hardware for installation.
