The 4112 motor is a “large diameter, super thick stack” design of a brushless outrunner motor. It is the “ultimate enhanced version” of the 4110 series, representing the peak of torque density and power density in the 41mm diameter platform. It is specifically designed for ultra-heavy, high-performance multi-rotor drones that have extreme power requirements and serves as the “ultimate power solution” for the most demanding flight missions.
Its core advantages lie in:
It offers the undisputed maximum torque and power in the same size class. Endow super-heavyweight unmanned aerial vehicles with powerful flight capabilities and control margins. Combined with high-pressure systems, it achieves relatively efficient and reliable operation under extreme performance conditions.
Choosing the 4112 motor means: Your project has absolute and the highest requirements for load capacity and power. You are building a platform that spares no expense in pursuit of ultimate reliability and performance. Conventional “high-performance” motors (such as 4110) can no longer meet your demand threshold.
