Electro-magnetic actuators are used in a wide range of industry and consumer products. We are focusing on applications of fluid power, such as valve or pump drives. Our main research topics about optimisation and improvement of electro-magnetic actuators are alternative manufacturing (e.g. injection moulding of magnetic material, 3D screen printing), new structures (e.g. energy efficient solutions, optimal functional structures) and condition monitoring (e.g. observation of armature position). There are many uncovered optimisation potentials such as precise thermal dimensioning and alternative manufacturing-oriented structures, which can be starting points for further research and development. Based on current applications of electro-magnetic actuators with its challenges, there can be numerous of other possible topics.
