Embodiment Construction
[0042]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0043] The purpose of the present invention is to provide a method for diagnosing inter-turn short-circuit faults of synchronous motor rotor windings based on multi-source information, which preserves the characteristics of the original signal to the greatest extent, eliminates the influence of manual extraction of characteristics, and avoids the failure of a single sensor when the fault occurs. The resulting phenomena such as missed ju...
