Abstract
Non-invasive rubbing detection for motors is disclosed. In an embodiment, a method of detecting rubbing on a stator of a motor includes providing an electrical conductor on the stator, (the electrical conductor has a first end and a second end). The method further includes determining that there is rubbing on a surface of the stator, including by probing the first end and the second end to determine whether there is an electrical connection across the electrical conductor, and determining that there is rubbing on the stator if there is no electrical connection. In an embodiment, the electrical conductor is disposed on the surface of the stator by etching away conductive foil to form the electrical conductor, and providing the electrical conductor.
