When the main winding of the shaded pole motor is energized, the shaded pole winding will also generate induced current, which will make the magnetic flux of the covered part of the stator pole and the uncovered part rotate in the direction of the covered part.
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.
