摘要

我们正在开发一种小型轻便的直接驱动系统，以实现轮内电动汽车（EV）。为了提高电机的功率密度，我们开发了一种直接冷却电机，将铁芯、线圈和磁体浸入冷却油中，提高了冷却效率。此外，我们在试验台上进行了摩擦损失测量、压降测量和连续热运转试验。结果表明，直接冷却是有效的，可以实现连续运行。此外，发现线圈温度可以通过冷却油的流速来控制。在本文中，我们报告了直接冷却的概念和测量结果。

Fundamental evaluation of direct-cooling technology for in-wheel drive system

We are developing a small and lightweight direct-drive system toward the realization of in-wheel electric vehicles (EVs). To increase the power density of the motor, we developed a direct-cooling motor that immersed the core, coils, and magnets in cooling oil and improved cooling efficiency. Moreover, we performed measurements of frictional loss, measurement of pressure drop, and a continuous heat-run test on the test bench. The results demonstrated that direct cooling is effective and continuous operation can be achieved. Additionally, it was found that the coil temperature can be controlled by the flow rate of the cooling oil. In this paper, we report on the concept of direct cooling and the measurement results.
