Title:
FAULT MEASUREMENT METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/046166
Kind Code:
A1
Abstract:
A fault measurement method, the method comprising: acquiring a first current of a motor; according to the first current, obtaining first feature data of the first current, the first feature data being related to a fault of the motor, the first feature data being the numerical relationship between a plurality of first harmonic amplitudes and a plurality of first amplitudes of the first current, the plurality of first amplitudes comprising a first fundamental wave amplitude and a plurality of second harmonic amplitudes of the first current, and the plurality of second harmonic amplitudes being unrelated to the fault of the motor; and according to the first feature data, determining the degree of fault of the motor. The present application can determine the degree of potential faults of the motor on the basis of the feature data.
