In order to improve product efficiency in the industrial field, it is important to know the flow of the cooling fluid inside the product. In the case of a motor, in order to make compact and lightweight, efficient cooling of the motor must be performed. However, it is difficult to see the flow of the motor. In this study, in-house code written by fortran language is used to visualize the flow in the motor. In this paper, calculations were made using the calculated shape of the concentric double cylinder simulating the actual machine. In addition, a solid assuming the core of the actual machine was inserted in the double cylinder. At that time, simulation of cooling was performed under the condition that the same rotation as the actual operating situation was added, and how each core was cooled was investigated. As a result, it was found that each core was not evenly cooled. Therefore, as future tasks, if the number of cores increases, we will consider ways to efficiently cool each core.
