Details

The T-Motor MN801S is positioned as a heavy-load motor for VTOL builds, with a stated takeoff weight range of 20–30 kg.

The T-Motor MN8017 features a central shaft mount and evenly spaced ventilation holes for straightforward installation.
T-Motor highlights 12+ kg thrust along with stable and reliable operation, impact resistance, and an IP45 rating.

The centrifugal fan bell cap and finned base are designed to move air through the motor for faster cooling, with text noting up to 15% improved cooling performance.

T-Motor airflow simulation emphasizes cooling-focused airflow design with anti-high temperature and anti-overload callouts.

The sectional temperature contour plot maps heat distribution across the motor components on a 292.75–406.22 K scale.

T-Motor MN801S motors feature an IP45 semi-closed design to help protect against dust, debris, and corrosion in challenging environments.

The MN801S motor uses a sealed, corrosion-resistant design intended to help handle wet and dusty operating conditions.


The MN801S uses a 12mm steel shaft and 24mm bearing size to support stable motor operation and durability.

T-Motor uses curved magnets with precise tolerance control and optimized spacing, stated to improve motor performance by 5%+.

The T-Motor integrated prop kit includes four M3×14 mm mounting screws and a Ø30×3 mm cover for installation on 26–32 inch props.

The T-Motor setup pairs a foldable 26–32 inch prop with an included set of four M4×10 mm mounting screws for secure installation.

T-Motor brushless motor design pairs with a carbon-fiber propeller mount for a clean, compact drive setup.

The T-Motor MN801-S KV120 features a clean silver motor can with clearly marked KV rating and a simple mounting pattern for straightforward installation.

T-Motor brushless motor hardware features a machined metal end-cap design with multiple mounting holes for secure installation.

A 10-minute, 100% throttle endurance test graph is included for reference.



T-Motor branding includes the “The safest propulsion system” tagline alongside the T-Motor logo.
