 · The architecture of the motor is a variant of what is known as an axial flux, or axial gap, machine. Because of their very low axial length-to-diameter ratio, axial flux motors are frequently referred to as 'flat' or 'pancake' motors. They produce a lot of torque, but their speeds are limited due to the rotor's design.

External rotor motors. External rotor BLDC 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 housing which rotates around the internal stator with the windings. Thanks to the higher inertia of the rotor, external rotor ...
