This paper presents a new search-coil scheme which makes it feasible to detect all faults in Permanent-Magnet Machines. The idea is based on two search-coils, one placed in the rotor and one in the stator, which couple magnetically under faulty conditions. The shape of the waveform is associated with the type of fault and the amplitude of the monitored sensor, with the severity of the fault. The studied faults are, the demagnetization, inter-turn, angular and axis misalignment faults. The proposed scheme is applicable to both type of machines, radial- and axial-flux. 2-D FEA results for the radial-flux machine and 3-D FEA results for the axial-flux show that the proposed method is promising for facilitating an experimental layout for condition monitoring applications.
