Management Device for Power Transmission Mechanism, Management Method for Power Transmission Mechanism, and Management System

Abstract

A management device that can sense abnormality (deterioration) detection on a power transmission mechanism with higher precision and probability is implemented. A management device 30 for a power transmission mechanism that transmits a driving force from an electric motor 13 to a load-side device 12 includes a current acquiring section that acquires a current value of the electric motor 13 per unit process in which the power transmission mechanism is driven, a feature calculating section 121 that divides the unit process into multiple zones and calculates an average current value obtained by averaging the current value of each of the zones, and a diagnosis section 122 that executes abnormality detection. The diagnosis section 122 calculates a state amount estimation value on the basis of the average current value of the multiple zones, and executes abnormality sensing in the unit process on the basis of the state amount estimation value.
