In a long stator linear motor, in order to implement a transfer position in which a transport unit (Tn) is magnetically steered in order to be redirected from a first transport section (Am) to a second transport section (An) and in order that the forward movement of the transport unit (Tn) remains as unaffected as possible by the transfer, it is provided that at the transfer position (U) on at least one side of the transport unit (Tn), the stator current (iA) of at least one driving coil (7, 8) interacting with an excitation magnet (4, 5) of the transport unit (Tn) is supplied as a current vector with a propulsive force-forming current component (iAq) and a lateral force-forming current component (iAd), and the stator current (iA) generates a propulsive force-forming electromagnetic force (FEMV) and/or lateral force-forming electromagnetic force component (FEMS) which is superimposed on the propulsive force (FV) acting on the transport unit (Tn) for production of a steering effect (L). |

1. A method for transferring a transport unit (Tn) of a long stator linear motor at a transfer position (U) from a first transport section (Am), having a number of driving coils (7, 8) arranged one behind the other in the direction of movement of the transport unit (Tn) in the region of the transfer position (U), to a second transport section (An), having a number of driving coils (7, 8) arranged one behind the other in the direction of movement of the transport unit (Tn) in the region of the transfer position (U), wherein on each side of the transport unit (Tn) excitation magnets (4, 5) are arranged which interact with driving coils (7, 8) in the region of the transport unit (Tn), and for movement of the transport unit (Tn) driving coils (7, 8) in the region of the transport unit (Tn) are in each case supplied with a stator current (iA) for generation of a magnetic flux (ψ) which generates a propulsive force (FV) acting on the transport unit (Tn), characterized in that, for transfer of the transport unit (Tn) at the transfer position, on at least one side of the transport unit (Tn) the stator current (iA) of at least one driving coil (7, 8) interacting with an excitation magnet (4, 5) of the transport unit (Tn) is supplied as a current vector with a propulsive force-forming current component (iAq) and a lateral force-forming current component (iAd), and the stator current (iA) generates a propulsive force-forming electromagnetic force (FEMV) and/or lateral force-forming electromagnetic force component (FEMS) which is superimposed on the propulsive force (FV) acting on the transport unit (Tn) for production of a steering effect (L). |
