Study on Appropriate Cooling Systems According to Output of Motor for Small EV’s 2017-32-0079

It is important to make small and light weight motor for small EV. It is necessary to select appropriate cooling system (liquid cool or air cool) according to motor output. We thought that there is a threshold output that makes the volume smaller and the weight lighter including the liquid cooling system.
As a result of the rough calculation, it was found that the weight can be reduced by adopting the liquid cooling for at about 10kW or more.
In this study we focused on motor and cooling system volume and weight and tried to clarify appropriate cooling system according to motor output.
