METHOD AND LONG STATOR LINEAR MOTOR FOR TRANSFERRING A TRANSPORT UNIT AT A TRANSFERRING POSITION
DRIVE
December 28, 2016
In order to realize a transfer position in a long-stator linear motor in which a transport unit (Tn) is magnetically guided to be deflected from a first transport section (Am) to a second transport section (An) while keeping the forward movement of the transport unit (Tn) 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 (i) of at least one drive coil (7, 8) cooperating with an excitation magnet (4, 5) of the transport unit (Tn) is impressed as a current space vector with a propulsion force-forming current component (i) and a lateral force-forming current component (i), and the stator current (i) generates a propulsion force-forming electromagnetic force component (F) and/or lateral force-forming electromagnetic force component (F), which is superimposed on the propulsion force (F) acting on the transport unit (Tn) in order to produce a steering effect (L).
