A linear transport system comprises a first carriage and a second carriage, a linear motor for driving the first carriage and the second carriage and a guide rail. The linear motor comprises a stator and a first and a second rotor. The stator has a plurality of drive coils that are arranged along the guide rail individual motor modules comprise a plurality of drive coils. The first rotor is arranged on the first carriage and the second rotor is arranged on the second carriage. The first carriage has a first magnetic field generator. The second carriage has a second magnetic field generator. The first magnetic field generator differs from the second magnetic field generator at least in terms of its magnetic vector field, wherein the magnetic fields of the magnetic field generators are detected to identify the corresponding carriage.
