The invention discloses an elevator power equipment fault detection method and device and an elevator system. The method comprises the following steps: acquiring running speed data of a driving part in elevator power equipment, and taking the running speed data corresponding to the running speed data when an elevator is at a first speed and within a preset duration as target data; according to the target data, calculating to obtain time domain signal data of acceleration; according to the time domain signal data, obtaining frequency domain signal data of acceleration through conversion; comparing the peak frequency forming a waveform peak in the frequency domain signal data with the characteristic frequency of the elevator power equipment, and judging that the elevator power equipment has a fault when detecting that at least one first frequency exists in the peak frequency, the first frequency is matched with one of the characteristic frequencies, and the amplitude of the first frequency exceeds a preset threshold value. The elevator power equipment fault can be detected and found in time, the field maintenance cost is reduced, and safe operation of an elevator is guaranteed.
