Abstract
A motor bearing wear monitoring device (A) monitors wear state of bearings () by using detection coils (Cto C). The device includes a division value calculation unit () calculating a division value by dividing a signal voltage of a first combined signal of a pair of thrust detection coils by a signal voltage of a second combined signal of another pair of thrust detection coils, among the detection coils, or by dividing the signal voltage of the second combined signal by the signal voltage of the first combined signal, and an initial value setting unit () setting an initial value indicating a position of the rotor in an unworn state, based on the division value at the initial position, the initial position being a position of the rotor in the thrust direction in the unworn state in which the bearings are not worn.
