when field winding is removed at that instant motor tends to
go for infinite speeds , but due to the presence of stator
,it stops because the flux is zero

why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
