MACHINE LEARNING DEVICE THAT LEARNS COOLING DEVICE OPERATING CONDITION, MOTOR CONTROL DEVICE HAVING MACHINE LEARNING DEVICE, MOTOR CONTROL SYSTEM, AND MACHINE LEARNING METHOD

摘要

PROBLEM TO BE SOLVED: To control the temperature of a motor and a motor control device by machine learning to keep it below a prescribed temperature, and reduce losses in the motor, the motor control device, and a cooling device.SOLUTION: Provided is a machine learning device 1 that learns a cooling device operating condition for cooling a motor or a motor control device, the machine learning device comprising: a state observation unit 2 for observing a state variable including at least one of temperature data at a specific place of each of the motor and the motor control device while the cooling device is operating; a determination data acquisition unit 3 for acquiring determination data for determining an allowance for a loss in each of the motor, the motor control device, and the cooling device and for a permissible value for the temperature at the specific place of the motor and the motor control device; and a learning unit 4 for learning a cooling device operating condition in accordance with a training data set constituted with a combination of the state variable and the determination data.SELECTED DRAWING: Figure 1
