A new technology for motor fault precise detection - Multi-frequency waves quantitive analysis method

In motor fault diagnosing finding out a method which could be used to calculate multi-frequency waves' peak values is a difficult theoretical problem. By developing multi-loop theory , this paper established a new technique multi-frequency waves quantitative analysis method , which is suitable for analysizing motor windings faults and eccentricity faults. By using it we deduced most faults characteristic frequency waves formulas and realized calculating several waves at the same time. The work of this paper made the theory basis for distinguishing most faults, deciding faults characteristic waves threshold values and bringing forth non-dimentional diagnosis characaters.
