Description

The BrotherHobby Tornado T5 3115 Pro 900KV motor is a professional brushless motor designed for heavy and long-duration flights on medium and large multi-copters. The model combines high efficiency, reliability, and durability thanks to its well-thought-out design and quality materials. The Tornado T5 3115 Pro is designed to operate with 5-8S LiPo batteries, providing powerful thrust while maintaining optimal weight and high thermal resistance.

The motor's configuration is 12N14P, which allows for stable RPM and high torque with minimal energy loss. This makes the motor ideal for tasks requiring high performance under sustained loads.

Design Features

The casing and bell cap are made of 7075 aluminum, ensuring high rigidity and wear resistance. The stator is made of 0.2 mm thick Kawasaki silicon steel, which reduces magnetic losses and increases efficiency. The rotor is equipped with N52H arc magnets, which enhance efficiency and torque. The hollow shaft made of titanium alloy reduces the mass of rotating elements and improves dynamics and inertial characteristics.

For smooth operation and durability, Japanese NMB bearings of size 11 mm × 5 mm × 5 mm are installed. The motor mounting pattern is M3 bolts with a 19×19 mm spacing, ensuring compatibility with standard frames, and the propeller adapter shaft thread is M5, compatible with common adapters.
