Electric motorcycle, electric vehicle, and cooling structure for electric vehicle

摘要

In the electric two-wheeled vehicle 1 including the traveling motor 20 and a power supply circuit such as an inverter, the non-conductive cooling member is brought into direct contact with at least one of the electromagnetic coil of the traveling motor 20 and the circuit board 60a of the inverter. Supply oil. A radiator 70 is disposed outside the case of the power plant 40 and the power control controller 60 so that the traveling wind passes. Cooling oil is circulated between the radiator 70 and at least one case of the power plant 40 and the power controller 60. Accordingly, it is possible to provide a cooling structure such as an electric motor that can obtain a higher cooling efficiency than the conventional one, while having a simple structure that is unlikely to cause an increase in size and weight and an increase in cost.
