The present application relates to elevator technology, in particular to a fault monitoring device and method for elevator motor and computer-readable storage medium on which computer programs (540) for implementing the method are stored. According to an aspect of the present application, there is provided a fault monitoring device for an elevator motor, comprising: a memory (520); a processor (530) coupled with the memory (520); and a computer program (540) stored on the memory and running on the processor (530), the running of the computer program (540) 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.
