Abstract
An electromagnetic actuator comprises two units, which, upon electromagnetic interaction, are configured to cause a guided movement relative to each other in translational and rotational directions with a bearing gap in between. The electromagnetic actuator is configured to supply compressed gas to the bearing gap to create a film of gas between the units constituting a frictionless floating bearing.
