Failure Diagnosis of Brushless DC Motor with Rotor Magnet Defect", IEEE 2011 International Electric Machines and Drives, pp.1561-1565, Niagara Canada, 2011.5.18
Abstract: This paper develops the failure diagnosis system for the brushless DC motor with demagnetized permanent magnets using Lab VIEW. The Fourier analysis and the Wavelet analysis of the amplitude of two-phase current are useful for the failure diagnosis method for the demagnetization of permanent magnets.
