With demanding technological features, you can see a drop-off in performance due to heat. AC fans are an excellent choice to maintain just the right amount of cooling for these components.
The construction of the motor is very simple because it does not contain any commutator, brushes, collector rings, etc. or any other part. The shaded pole induction motor does not have any centrifugal switch. Thus, the chances of failure of the motor are less.
DC brushed torque motors (consisting of a rotor, stator, and brush ring assembly) are designed in as an integral part of a system thus saving weight and space.
