Scope
Efficient Oil Cooling of electric machine: 
All rotating electrical machines generate heat as a result of the electrical and mechanical losses inside the machine. Using oil cooling is a highly effective way to run the electric machine in the best way and to improve efficiency and reliability. 
 

To refine the current concept design. We would like to study the Oil Cooling of copper windings and stator, but at the same time prevent oil from entering the air gap between the rotor and stator to prevent losses. Oil in air gap can create 10-20 times higher losses.

Activities we foresee that should be done during this thesis work are: 
•    Benchmarking of competitors.
•    Create a 3D design of the concept
•    Prototype evaluation
•    Perform testing in rigs.
