Electric vehicles require highly performant motors to be able to compete with conventional internal combustion engines. One of the issues when aiming to improve the power output of an electrical motor is overheating of the current carrying windings in the motor. A novel cooling method, mid-conductor winding cooling, has been shown in previous experimental studies to significantly improve the cooling of the windings. This techniques brings a dielectric coolant in direct contact with the wires of the winding. However, the long-term stability of the method still needs to be proven.


The goal of this thesis is to analyze the effect of mid-conductor winding cooling on two key aspects of the electric motor: electric and mechanical. From the electrical side, it should be analyzed if the electrical insulation around the wires is not affected by degradation and/or wear over time. From the mechanical side, the structural strength of the winding and possible occurrence of vibrations and related noise needs to be investigated. An experimental setup will be designed to be able to test and quantify these effects.

This project aids in achieving sustainable development goal (SDG) 7: affordable and clean energy, by enabling the replacement of fossil fuels by renewable electricity as an energy source for the transport sector.
