Outer rotor brushless dc motor a rotor inside and a much higher moment of inertia of the rotor (on the main quality is concentrated in the shell of the rotor), so the speed slower than inner rotor motor, which can be used to directly drive the load, and eliminate the mechanical retarding mechanism, especially suitable for low speed high torque, small volume, high output power.

Outrunner BLDC motors, also known as external rotor brushless motors, are a type of motor where the rotor is located on the outside of the stator. These motors are commonly used in applications such as remote-controlled models, electric vehicles, and robotic systems. With their unique design, outrunner BLDC motors offer high torque and efficient power delivery.

Big brushless motors (big bldc motor) refer to larger-sized brushless motors that are often utilized in industrial equipment, unmanned aerial vehicles (UAVs), and electric vehicles requiring high power output. These motors provide robust performance and can handle heavy-duty applications with ease.

High RPM brushless motors are designed to achieve impressive rotational speeds. Outrunner brushless motors are commonly used in applications where rapid rotations are required, such as cooling fans, high-speed tools, and model aircraft. These motors deliver exceptional speed and responsiveness, making them ideal for applications demanding quick and precise movements.
