Energy efficiency in urban electric transport: advancements in traction electric motors with liquid cooling systems

Abstract

The contemporary development of electric transport in Ukraine is marked by a concerted effort towards the creation of energyefficient technologies in energy conversion systems. Central to these systems is the traction drive, where the type of traction motor employed determines its characteristics and technical solutions. Among the promising technologies for developing energy-efficient traction motors, liquid cooling systems emerge as particularly noteworthy, offering the potential to significantly enhance their weight-to-power ratio. The exploration and development of liquid cooling technologies for traction motors not only unlock new possibilities but also pave the way for the creation of low-floor urban electric transport vehicles.
