Due to the accommodating space of this configuration, the vehicle is equipped with Conditions such as weight, driving type, and tire size limit the motor power.

Due to the above factors, most electric locomotives currently have non-forced cooling motors with a peak power of about 4kW or less. Therefore, there are no external components such as fans, pumps, etc. for forced air or liquid cooling, and only the air flow generated when the electric locomotive is moving. Cooling, its performance is easily affected by riding speed and the external environment. For example, when climbing a hill, the motor and drive controller generate a lot of heat, but at this time, the vehicle speed is low, so the heat dissipation performance is poor, such as high ambient temperature and dust coverage. Factors, resulting in low heat exchange rate, heat dissipation performance is also affected.
