Disclosed is a linear synchronous motor comprising an elongate stator extending in a longitudinal direction and having a plurality of coil windings, and a runner having a multiplicity of successive magnets disposed along the length thereof the longitudinal direction. The elongate stator has a plurality of elongate-stator segments arranged successively in the longitudinal direction, with each elongate-stator segment separated from the next successive elongate-stator segment by a gap. A total section length of one elongate-stator segment and an adjacent gap is a constant value over a plurality of successive elongate-stator segments, wherein a runner length measured in the longitudinal direction across all magnets successively disposed on the runner, is an integer multiple of the total section length.

In order to improve control of a long-stator linear motor, a first measured value is ascertained in a first measurement section and a second measured value is ascertained in a second measurement section, in each case along a transport path in a movement direction. The first measurement section overlaps, in the movement direction, the second measurement section in an overlap region, and the first measured value and the second measured value represent the same actual value of a physical quantity. An operating parameter of the long-stator linear motor determined based on a deviation occurring between the first measured value and the second measured value.
