Abstract
The motor bearing wear state estimation device (5, 5A) estimates a wear state of bearings (32, 33) by using a plurality of detection coils (C1 to C8). The device includes a storage (56, 56A) storing a first learning model (M11, M21) and a second learning model (M12, M22), a retrieval unit (550) retrieving each signal, and an estimation unit (551) estimating the wear state by inputting a first difference signal, a second difference signal, and an amplitude signal into the first learning model, and by inputting a thrust difference signal and the amplitude signal into the second learning model. The amplitude signal is a first amplitude signal generated based on each detection signal of first radial detection coils and/or each detection signal of second radial detection coils, or a second amplitude signal generated based on a first combined signal and a second combined signal.
