Abstract
Method for operating a transport apparatus that utilizes a long stator linear motor, the method includes moving a transport unit along a transport route of the long stator linear motor, causing drive magnets arranged on both sides of a main body of the transport unit to interact, at least in a region of a transfer position for transferring the transfer unit between two opposite route portions of the transport route, with drive coils of the opposite route portions of the transport route in order to generate a propulsive force (Fv), utilizing the drive magnets of the transport unit and the drive coils of the transport route of the long stator linear motor as sources of magnetomotive force of a magnetic circuit that develops at least in the region of the transfer position on both sides of the transport unit, and transferring the transport unit between the opposite route portions of the transport route in the transfer position by changing on at least one side of the transfer unit a magnetic flux (Ψ1, Ψ2) of the magnetic circuit of the at least one side during movement of the transport unit along the transport route in order to generate a lateral force acting on the transport unit.
