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.

In a converter motor, the converter unit and the electric motor together form a mechatronic unit. The converter unit is located behind the electric motor and is thermally coupled with the rear bearing shield. The converter unit includes a through hole, through which the rear end of the motor shaft passes. A contactless position detector is located in the region of this through hole.

A linear motor includes a primary part arranged as a guideway stator and at least one secondary part that is movable with respect to the primary part, the at least one secondary part having device(s) for controlling the generation of a magnetic field, causing its motion, in the primary part. It is possible to avoid costly control devices for the application of current to the stator.
