Electrical Machine Oil Cooling

// About Thesis Work

Thermal management is a key aspect when designing electrical machines in general, and even more so in automotive traction systems. Most electrical vehicles on the road today tend to use water jacket cooling and/or spray oil cooling of some kind. The spray oil cooling typically provides superior performance but comes with the drawbacks of increased cost, weight, and complexity due to the added components (pump, heat exchanger, filter).

The objective for this thesis work will be to evaluate the cooling performance of some novel concepts and compare them to water jacket cooling on an automotive traction electrical machine. The evaluation should preferably contain both simulations and measurements on a prototype of the novel concepts based on an existing electrical machine. A key metric will be the continuous current density for each cooling concept.


// Your Profile

You are a (or a plurality of) Master Student(s) in Engineering, you have at least basic knowledge of electrical machines, thermodynamics, fluid mechanics, measurement systems, and manufacturing methods. It will help to have some practical skills as the intention is to build and test.

Communication in English or Swedish is a requirement. The thesis shall be written in English.

Kristoffer Nilsson, System Architect & Technical Lead, Alvier Mechatronics,



Alvier Mechatronics is a fast-growing start-up engineering service company with colleagues in Sweden, Germany, and the US. We are a reliable partner of leading global automotive and industrial companies by providing development for e-drive systems. We offer a fast track from concept through design, simulation, prototyping and validation. Combining system, design and material competence, we optimize  eDrives for a sustainable future.

The development of e-drives goes far beyond the electric machine. To achieve increasingly challenging requirements on cost, efficiency, performance and sustainability, an efficient interaction of motor, power electronics, mechanical integration as well as the control strategy is required. Together with our industrial and academic partners, we cover a wide range of expertise in design and multiphysics simulations, electric motors, power electronics and transmissions.

Creativity, Entrepreneurship, and Innovation are our values which guide us everyday. Our mission is to offer a good and meaningful workplace where you develop and reach your full potential. We welcome all applicants and strive for diversity. Welcome to join a global team with exiting assignments and highly engaged employees.
