HOMAG

High-performance magnetic materials based on SmCo and CoFe for highly efficient electric automotive engines and aircraft engines

Context and topic

The mobility of people and goods is an important prerequisite for our society. The necessary means of transport on land, water and in the air all require increasingly powerful engines. In road traffic and aviation in particular, huge amounts of fossil resources in the form of petrol, diesel and kerosene are still burned in engines and turbines. On the one hand, this is not sustainable because of the limited deposits and, on the other hand, the released CO2 accelerates climate change, both of which represent a heavy burden for future generations.
The electrification of powertrains is the most promising approach to solve these challenges. The limited storage capacity of the currently available battery systems leads to the urgent need to increase the efficiency of electric drives. In addition, especially in the field of aviation, the volume and weight of propulsion systems are limiting factors and must be reduced as far as possible in order to enable the use of certain technologies and to conserve resources.

Goal

The aim of the HOMAG project is the development of temperature-stable SmCo permanent magnets with highest energy density and a cost-efficient procedure for stacks of CoFe sheets, in order to drastically reduce the size, weight and losses of electric drives for transport systems. The newly developed high-performance magnetic materials will be used to build and test demonstrator motors for an automobile engine and an aircraft engine on behalf of other drive systems.

Funding code

The HOMAG project is funded by the Federal Ministry of Education and Research (BMBF).
