External rotor motor refers to the motor with rotating shell and fixed shaft. This motor has the characteristics of space saving, compact design and beautiful appearance. It is suitable for installation in impellers for optimum cooling. Therefore, no V-belts, additional tension straps or other equipment are required. The motor uses a pair of sealed deep groove ball bearings for long life. High precision ball bearings can minimize vibration and reduce running noise.

High-sensitivity thermal protector is installed at the winding end of the motor to ensure safe and reliable operation of the motor. Since this motor has large torque, therefore it is appropriate for a large propeller, and has high efficiency. In addition, it is widely used in various electric drones.
