Machine learning device, motor control system, and machine learning method for learning cleaning interval of fan motor

摘要

A machine learning device which learns the cleaning frequency of a fan motor which cools an electric motor mounted in a machine includes a state observation unit which observes the state of the machine, and a learning unit which updates an action value table for cleaning the fan motor, on the basis of a state variable observed by the state observation unit. This can improve both the life of the electric motor and the operating ratio of the machine.
