Overview
T-Motor AM480 B Version KV900 is a brushless motor designed for 48-52 in 3D airplane models. The motor uses a rippled motor bell and a hollow shaft for improved robustness with reduced weight, and a 3:1 diameter-to-height ratio for higher torque and better cooling.
Structural design notes shown on the product images include: “Lighter and more durable achieving load-free flight”, and a staggered front cover strip for higher strength. Marked weight details: front cover strip 3g; no back cover 5g.
Key Features
- Suitable for 48-52 in 3D plane
- Rippled motor bell and hollow shaft design (robust and lighter vs. predecessors)
- 3:1 diameter-to-height ratio (higher torque and better cooling)
- Adjustable prop adapter and dual color craft
- Staggered front cover strip for higher strength (as shown)
Recommended Setup
- Frame: 48-52 in 3D plane
- Recommended ESC: AM66A
- Recommended propeller (KV900 column shown): 12*6 (for light weight), 13*6.5 (for high efficiency), 14*7 (for extreme flight)

Details

The AMAX motor uses an open-frame design with a front cover strip to help keep the build light and rigid.

AM480 motor setup guidance lists KV600/KV650/KV900 cruising power, a recommended AM 66A ESC, and suggested 12x6, 13x6.5, and 14x7 propeller sizes.

Detailed dimensional views and the mounting hole pattern help confirm fitment for the hub, shaft, and bracket during installation.

T-Motor KV600/KV650/KV900 options list key specs like 49×70mm size, 145g weight, 3–6S voltage range, and peak current up to 60A.

The T-Motor AM480 KV600 test report lists throttle, RPM, thrust, efficiency, and current for APC 12×6 and 13×6.5 propellers.

T-Motor AM480 KV600 bench-test results list throttle, voltage, current, power, RPM, torque, thrust, efficiency, and operating temperature with 13x6.5 props.

T-Motor AM480 KV650 performance data is listed for APC 12×6 and 13×6.5 propellers, including voltage, current, RPM, thrust, and efficiency.

T-Motor AM480 KV650 bench test data lists voltage, current, power, RPM, torque, thrust, efficiency, and operating temperature across throttle settings with 13×6.5 propellers.

The AM480 KV900 performance table lists voltage, current, RPM, torque, thrust, and efficiency results at different throttle settings with various propellers.

The T-Motor AM480 KV900 motor comes with a parts bag including an X-mount, spacers, screws, and a small wrench for installation.
