.FeedDriveLibrary.FeedDriveMotor.Components.EMF .FeedDriveLibrary.FeedDriveMotor.Components.EMFEMF transforms electrical energy into rotational mechanical energy. It is used as basic building block of an electrical motor. The mechanical connector flange can be connected to elements of the Modelica.Mechanics.Rotational library. flange.tau is the cut-torque, flange.phi is the angle at the rotational connection.
