Machine learning device for learning operating condition of cooling device, motor control device, machine control system and machine learning method provided with machine learning device

摘要

A machine learning apparatus and method, a motor control apparatus and a motor control system are provided. The machine learning apparatus is a machine learning apparatus which learns the operation conditions of a cooling device for cooling a motor or a motor control apparatus. The machine learning apparatus is characterized by comprising a state observer for observing a state variable including at least one of temperature data of the motor and the motor control apparatus at a specific position during operation of the cooling device; a determination data acquisition unit for acquiring determination data that determines a margin of acceptable value of a loss in each of the motor, the motor control apparatus, and the cooling device and a margin of acceptable value of the temperature of each of the motor and the motor control apparatus at the specific position; and a learner for learning the operation conditions of the cooling device in accordance with a training data set constituted of a combination of the state variable and the determination data.
