Outer Rotor Brushless DC Motor 42mm
Electrical Specification
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. The 42mm, 60mm, 75mm and 90mm outer rotor brushless DC motors can be applied to robot, AGV, turnstile, coffee maker and so on.
