Abstract: The invention relates to an electric media gap machine (10) for a compressor (2) and/or a turbine (3), in particular for a turbocharger (1) of an internal combustion engine, comprising a shaft (5) which is rotatably mounted in a housing (6) and to which a rotor (11) is rotationally fixed, a stator (12) which is fixed to the housing and which has at least one multiphase drive coil (16) for generating a drive magnetic field and multiple stator teeth (15) which protrude inwards radially. The drive coil (16) is designed as at least one flat conductor coil (17) which is wound about the stator teeth (15) and which has coil heads (18, 19) projecting axially on both sides on the stator (12). The drive coil (16) has an end-face depression (21) on at least one of the coil heads (18, 19) for receiving a section of the housing (6) in at least some regions.

Abstract: A method for operating an axial piston machine of swashplate design, in which a swashplate is settable by means of an adjustment device, and in which a controlled variable of the axial piston machine is regulated by predetermining a manipulated variable. Under the assumption of a constant intended value of the controlled variable, a future profile of the controlled variable is ascertained using a model of the axial piston machine in which respective current values of at least one operating variable of the axial piston machine, which comprises the controlled variable, and a current value of the manipulated variable are taken into account. A value to be set for the manipulated variable is ascertained and set taking into account the future profile of the controlled variable.

Abstract: A method for controlling a hydrostatic drive, which has a driving engine, a hydraulic pump coupled to the driving engine and a hydraulic motor coupled to the hydraulic pump by way of a pressurized hydraulic work line, includes calculating a manipulated variable vector comprising at least one manipulated variable for the hydrostatic drive based on (i) an output torque setpoint value for a torque on a secondary shaft driven by the hydraulic motor, (ii) a rotational speed and torque of the driving engine emerging from a predetermined operating point characteristic for the driving engine, and (iii) volumetric and mechanical losses of at least one adjuster unit comprising the hydraulic pump and the hydraulic motor. The manipulated variable vector is used to control the hydrostatic drive.
