what's the difference between a shaded pole motor and a brush type motor ?
A Shaded Pole Motor is a Brushless type, Single Phase Squirrel Cage Induction Motor, with a Short Circuited "Secondary" (Rotor), and a Shading Pole in the "Primary" (Stator) for Starting.
A Brush type Motor has Brushes contacting a Commutator, which is mounted on a rotatable, wound Armature.
The Commutator segments feed to/from the Windings on the Armature assembly.
There are a few AC Induction Motors with Commutators & Brushes (Syncronous, Repulsion Start, etc.), but for the most part, Induction Motors are Brushless Animals, with the Stator (Primary) Windings Physically Isolated (not connected in a "Physical" way), from the Rotor (Secondary).
The Stator would kind of equate to the Field windings of a Commutator Motor, and the Rotor equates to the Armature of a Commutator Motor.
They work nothing like one another - one functions via Induction, the other Repulsion.
