Abstract— Permanent magnet motors with magnets installed on
the rotor are widely employed in various fields due to their
excellent efficiency and output density. However, magnets are
susceptible to irreversible demagnetization faults, where their
magnetic properties degrade due to stresses such as external
magnetic fields and high temperature condition. Irreversible
demagnetization faults can deteriorate motor performance and
even lead to catastrophic failures like control failures.
Furthermore, due to the uneven distribution of stresses, such as
heat and magnetic flux, on the motor magnets, irreversible
demagnetization faults exhibit non-uniformity along the z-axis
direction. Therefore, there is a need to study diagnostic techniques
for irreversible demagnetization faults. Various diagnostic
techniques have been proposed; however, most of them cannot
provide diagnostics for individual magnet segments. In this paper,
we introduce a fault diagnosis technique using planar search coils
attached to the surface of the motor's stator. The planar search
coils can be fabricated in various shapes, allowing for the
arrangement of multiple coils along the z-axis of the motor to
acquire signals based on the flux crossing each coil. This technique
is validated through finite element analysis and experiments. As a
result, it is confirmed that the proposed technique allows for fault
diagnosis in both the non-excited and excited states using the
acquired signals.
