Thermal management strategies and power ratings of electric vehicle motors

Abstract

This study offers a comprehensive exploration of the cooling strategies and power ratings of electric vehicle motors. Electric vehicles depend on robust electric motors for propulsion. High power and sustained high-speed usage create excessive heat, risking motor failure without effective thermal management. Implementation of effective cooling strategies thus becomes imperative to ensure both the longevity and optimal performance of electric vehicle motors. This article seeks to review range of cooling approaches, encompassing air cooling, liquid cooling, and hybrid cooling, scrutinizing their respective capabilities in efficiently dissipating the heat generated during motor operation. Furthermore, the study investigates the impact of power ratings on the performance of electric vehicle motors in determining its maximum power output with higher ratings. In summary, this article underscores the critical importance of carefully selecting the appropriate cooling strategy and power rating for electric vehicle motors to maximize their efficiency and durability. This insight proves to be invaluable to electric vehicle manufacturers and designers, providing them with essential guidance in the design and selection of electric vehicle motors that meet the demands of modern transportation while contributing to a sustainable future.
