Outrunner Brushless Motor

Outrunner brushless motor is a kind of low KV high power brushless motor. The magnets of the outer rotor motor are attached to the rotor housing, which means more kinetic energy can be obtained in a smaller interior space. Due to the higher moment of inertia of the rotor, the torque ripple of the outer rotor motor is smaller than that of the inner rotor motor. From the cost of the motor, the outer rotor is more economical and more powerful
