External rotor motors are shorter than internal rotor motors and offer a cost-effective solution particularly for large series. In these motors the permanent magnets are mounted on the rotor bell which rotates around the internal stator with the windings. Thanks to the higher inertia moment of the rotor, external rotor motors have a lower torque ripple than internal rotor motors.
