The use of advanced techniques for monitoring permanent magnet (PM) motors, and the diagnostic procedures aimed at monitoring their magnets’ health, in particular, are growing in importance. This paper presents a composite magnetostrictive Fibre Bragg Grating (FBG) flux sensor design aimed at facilitating straightforward in-situ installation in air-gaps of conventional PM motor topologies and enabling in-situ observation of different rotor PM magnetization levels. The sensor design is presented, involving the integration of Terfenol-D powder and an FBG sensor in an epoxy resin matrix within a dedicated 3D printed wedge enabling easy retrofit into the motor’s stator slot. The flux sensor in-situ performance is then tested and verified in tests involving different magnetization levels on the test motor’s PM rotor.
