I'm trying to figure out if a motor like this one

Is kaput or not, it has 4 wires, 2 are neutrals that are tied together in a choc block & 2 are I'm assuming live inputs that go into the timer control board.

I've done a few tests & 1 live input has about 10ohms to neutral but the other appears to be open circuit suggesting a coil has burnt out or maybe some internal thermal protection has tripped?

Can anyone say if I'm barking up the right tree :)

Ps what is this motor type called? Does it have a name?

Figured out its a shaded pole motor, just need to know if it has 2 separate windings & why 1 appears open circuit.
 
Various reasons fro having two windings Most common would be a dual voltage motor ( 110~ windings in parallel or 230~ windings in serial ).

Far less common is using the fan motor as a transformer to supply an isolated supply for some purpose.

The second winding may be a sense coil to detect a stalled fan but most unlikely in any domestic equipment where a vane in the air flow or a pressure switch would be used to detect fan failure.
