Long stator linear motor and method for moving a transport unit of a long stator linear motor

摘要

To the transition of a transport unit of a long stator linear motor via control zones (RZk, RZk + 1) with a number of drive coils (ASk.1, ..., ASk.m, ASk + 1.1, ..., ASk + 1.m), each control zone (RZk , RZk + 1) is controlled by a segment control unit (SRk, SRk + 1), it is provided that when the transport unit (Tn) moves from the first control zone (RZk) in the direction of movement (x) to the subsequent second control zone ( RZk + 1), first the first segment control unit (SRk) remains responsible for the control of the movement of the transport unit (Tn) and the first control zone (RZk) in the direction of movement (x) by a number (j) of virtual drive coils (ASk.m + 1 , ..., ASk.m + j) is extended, and the first segment control unit (SRk) assigned to the first control zone (RZk) also calculates the required manipulated variables for the required virtual drive coils (ASk.m + 1,..., ASk.m + j) , the first segment control unit (SRk) the required St ellizes for the required virtual drive coils (ASk.m + 1,..., ASk.m + j) to the second segment control unit (SRk + 1) assigned to the second control zone (RZk + 1) and the second segment control unit (SRk + 1) transmitted manipulated variables for the required virtual drive coils (ASk.m + 1, ..., ASk.m + j) for energizing the required for moving the transport unit (Tn) drive coils (ASk + 1.1, ..., ASk + 1.m) of the second Control zone (RZk + 1) used.
