Abstract

The present invention relates to a mover for a longitudinal stator system, comprising a primary part with elements for movably arranging the mover on a longitudinal stator and an accommodating area, in which a sensor for position-dependent measurement of at least one system parameter is arranged, the sensor being releasably connected to the accommodating area, and to a corresponding method for determining a system parameter of a longitudinal stator system.

First claim

The invention claimed is:

1. A mover for a longitudinal stator system, comprising a primary part with elements for movably arranging the mover on a longitudinal stator and an accommodating area, in which a sensor for position-dependent measurement of at least one system parameter is arranged, the sensor being releasably connected to the accommodating area, wherein the sensor comprises a load cell, which is connected to the mover in a stationary manner, and a secondary element corresponding to a secondary part of the mover as regards its geometry and/or a magnetic force exchangeable with the longitudinal stator during operation, wherein the load cell is able to measure a force acting on the secondary element when the mover moves along the longitudinal stator under an influence of a magnetic force.

2. The mover according to claim 1 , wherein the position of the load cell relative to the primary part can be adjusted by means of adjustment elements.

3. The mover according to claim 1 , wherein, in a condition in which the mover is arranged on the longitudinal stator, distance between the mover and the longitudinal stator perpendicular to a plane of movement of the mover along the longitudinal stator corresponds to a nominal distance between the mover with an installed secondary part and the longitudinal stator.

4. The mover according to claim 3 , wherein the load cell is configured for measuring, in both directions perpendicular to the plane of movement of the mover along the longitudinal stator, a force acting on the secondary element.

5. The mover according to claim 1 , wherein the sensor comprises a distance meter for measuring the distance between the mover and the longitudinal stator perpendicular to the plane, in which the mover can move along the longitudinal stator during operation.

6. The mover according to claim 5 , wherein the distance meter comprises one of:
one or a plurality of sensing rollers and/or
one or a plurality of sensing pins.

7. The mover according to claim 1 , wherein the mover comprises a position determination system, which is configured for determining a position of the mover along the longitudinal stator.

8. The mover according to claim 1 , further comprising an evaluation electronics for processing at least measurement values recorded by the sensor.

9. A method for determining a system parameter of a longitudinal stator system, wherein a mover comprising a primary part with elements for movably arranging the mover on a longitudinal stator and an accommodating area, in which a sensor for position-dependent measurement of the system parameter is arranged, wherein the sensor is releasably connected to the accommodating area, on the longitudinal stator and wherein the method comprises the sensor measuring at least one system parameter while the mover is arranged on the longitudinal stator, wherein the sensor comprises a load cell, which is connected to the mover in a stationary manner, and a secondary element corresponding to a secondary part of the mover as regards its geometry and/or a magnetic force exchangeable with the longitudinal stator during operation, wherein the load cell measures a force acting on the secondary element when the mover moves along the longitudinal stator under the influence of a magnetic force.

10. The method according to claim 9 , wherein the sensor measures the system parameter while the mover is moving along the longitudinal stator.

11. The method according to claim 9 , wherein the sensor measures the distance between the mover and the longitudinal stator by means of a distance meter for measuring the distance between the mover and the longitudinal stator perpendicular to the plane in which the mover moves along the longitudinal stator.

12. The method according to claim 9 , wherein values for the system parameter measured by the sensor are processed by means of an evaluation electronics of the mover.

13. The method according to claim 9 , wherein the position of the mover during a movement along the longitudinal stator is determined by means of a position determination system.
