Autonomous Cooling of the Future
Optimal design of an electrical machine aims first and foremost for the highest electromagnetic performance. The definition of its cooling system generally comes at the end of the design process and must adapt to electrical constraints while ensuring integrity and reliability.
However, significant temperature rises have a strong impact on operating safety and machine life. Temperature also has a strong impact on machine efficiency, as it affects the electrical resistance of the windings and can even generate thermal runaway phenomena.
As a result, an efficient cooling system improves the machine's efficiency and lifetime, and even its compactness.
In this project, several passive cooling techniques are studied experimentally and numerically. Among these techniques Phase Change Materials (PCMs) such as kerosene, salts...are explored. Initially, experimental qualification tests of PCMs are carried out in a simple configuration using a heated PCM tank. The best candidate is then tested in the case of a machine : in the stator and on the coil heads.
