ST5215 MultiRotor Motor

The 5215 motor is the ultimate embodiment of the “super-large platform, extreme volume” design philosophy. It is no longer an optimization of a single performance metric, but rather, by maximizing the stator volume, it has established an overwhelming absolute advantage in all dimensions such as torque, power, and thermal capacity. It is specifically designed for national-level or super-large enterprise projects that have ultimate demands for “absolute power” and “absolute reliability”, such as: prototypes of hundred-kilogram heavy logistics drones, large special engineering drones, and the lift systems of the next-generation heavy eVTOL aircraft.

The nearly maximum physical dimensions achievable through the current project provide an unparalleled benchmark for torque, power and thermal management. It provides the previously missing key power foundation for the application of unmanned aerial vehicles with a payload of over 100 kilograms and a flight range of several hours. The performance grade and reliability standards it represents are setting a new benchmark for the super-heavyweight unmanned aerial vehicle industry.
