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.
