Abstract

A production machine includes an electrical positioning drive having a stator and a moveable member displaceable relative to the stator in at least one travel direction. The moveable member is mounted, in relation to the stator, in a contactless manner by a magnetic field in at least one of the supporting directions differing from the travel direction. A sensor device is associated with the positioning drive to shift the moveable member relative to the stator in the supporting direction to be detected. A control device is also associated with the positioning drive, and the shift of the moveable member is detected by the sensor device and can be supplied in the supporting direction. A control signal for a positioning magnet system can be determined by the control device, on the basis of the shift of the moveable member in the supporting direction and a nominal positioning of the moveable member. The positioning magnet system can monitor the positioning of the moveable member in relation to the stator in the supporting direction in a non-contact manner. The control signal can be emitted to the positioning magnet system by the control device.

Claims7

Dependent claims

A production machine, in particular a machine tool and/or robot, comprising:

at least one electric positioning drive comprising a stator and a moveable member moveable relative to the stator in at least one travel direction, wherein the moveable member is contactless supported relative to the stator by a magnetic field in at least one support direction that is different from the at least one travel direction,
a sensor device operatively connected with the at least one positioning drive for contactless detection of an actual displacement of the moveable member relative to the stator in the at least one support direction,
a control device operatively connected with the at least one positioning device and receiving the actual displacement of the moveable member relative to the stator in the at least one support direction detected by the sensor device, wherein the control device determines from the actual displacement and a desired support position of the moveable member relative to the stator an actuating signal,
a positioning magnet system receiving from the control device the actuating signal and contactless correcting the actual displacement of the moveable member relative to the stator in the at least one support direction based on the actuating signal.
