This motor can be designed and made into a customized type according to your requirement.

Advantages
Compared with the inner rotor motor, the flat outer rotor brushless motor has a more compact structure and lower torque ripple.
Under the same volume, the outer rotor brushless motor will output a greater torque than the inner rotor motor.
