A method is used to control a torque of an electric motor of an electro-hydraulic system. The method includes selecting a value of a set point torque depending on a current pressure in a hydraulic circuit of the electro-hydraulic system. The method also includes determining a control signal for controlling the torque of the electric motor using a target torque and the set point torque.

Method and device for controlling a torque of an electric motor of an electro-hydraulic system

A contactless energy supply for electrical consumers mounted on the mobile part of a linear motor is provided, the energy supply being provided without additional voltage sources. A higher frequency energy supply field is superposed over the propulsion field, the energy supply field being inductively decoupled using the energy transmitting interface of the secondary part, and supplying consumers mounted on the secondary part with energy.

In a linear motor and its progressive motion or motion control, e.g., for modular transport devices with straight and curved route sections forming a route course, extensive modularity or flexibility of the linear motor may be guaranteed with little expenditure in terms of equipment and software, e.g., with regard to various applications or machine configurations, e.g., when a plurality of secondary parts are used. A secondary part may have at least one permanent magnet and a signal processing device with a progressive motion or motion controller, which generates at least one set value relevant to the coil control. A set value is fed as a magnitude for commutation using a set value interface of a coil control that is stationary relative to the primary part. Device(s) are also provided for rigidly positioning the secondary part, the device(s) guiding the secondary part along a predetermined stretch.
