A fault monitoring device and method for elevator motor and computer-readable storage medium on which computer programs for implementing the method are stored. A fault monitoring device for an elevator motor, includes: a memory; a processor coupled with the memory; and a computer program stored on the memory and running on the processor, the running of the computer program causes: A. determining one or more components of a stator coil current at one or more characteristic frequencies from a measurement of the stator coil current of the elevator motor; and B. determining, based on the one or more components, whether a fault of turn-to-turn short circuit occurs in the stator coil.
