Abstract
Official abstract text for this publication.
In order to implement a transfer position in a long-stator linear motor, in which position a transport unit is magnetically steered in order to be deflected from a first transport sections to a second transport section, a stator current is impressed into the drive coils interacting with the transport unit on a first side of the transport unit in the transfer area in order to generate the steering effect on this first side, which stator current either generates only an electromagnetic lateral force or causes only a braking force against the movement direction of the transport unit, or only a combination thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for transferring a transport unit of a long-stator linear motor at a transfer position from a first transport section, having a number of drive coils arranged one behind the other in the movement direction of the transport unit in the area of the transfer position, to a second transport section, having a number of drive coils arranged one behind the other in the movement direction of the transport unit in the area of the transfer position, wherein excitation magnets being arranged on each side of the transport unit, which excitation magnets interact with drive coils in the area of the transport unit for moving the transport unit in the movement direction by generating an electromagnetic field by impressing a stator current into drive coils, which electromagnetic field interacts with excitation magnets on the transport unit and wherein a stator current is impressed into at least one drive coil in a transfer area of the transfer position on at least one side of the transport unit, which stator current generates a steering effect on the transport unit due to a propulsive force-forming current component and/or a lateral force-forming current component of the stator current, characterized in that in the transfer area a stator current is impressed into the drive coils interacting with the transport unit on a first side for generating the steering effect on this first side of the transport unit, which stator current either generates only an electromagnetic lateral force or generates only a braking force against the movement direction of the transport unit, or only a combination thereof. 2. The method according to claim 1 , wherein in the transfer area on an opposite second side of the transport unit no stator current is impressed into at least one drive coil interacting with the transport unit on this second side. 3. The method according to claim 2 , wherein no stator current is impressed into all drive coils interacting with the transport unit on the second side. 4. The method according to claim 1 , wherein in the transfer area on an opposite second side of the transport unit a stator current is impressed into at least one drive coil interacting with the transport unit on this second side, which stator current causes an electromagnetic lateral force. 5. The method according to claim 4 , wherein a stator current is impressed into all drive coils interacting with the transport unit on the second side, which stator current causes an electromagnetic lateral force. 6. The method according claim 1 , wherein in the transfer area on an opposite second side of the transport unit a stator current is impressed into at least one drive coil interacting with the transport unit on this second side, which stator current causes an electromagnetic propulsive force. 7. The method according to claim 6 , wherein a stator current is impressed into all drive coils interacting with the transport unit on the second side, which stator current causes an electromagnetic propulsive force.
