A linear motor is disclosed, which has a stator and at least one rotor, the stator having at least two stator modules. Each stator module has a coil arrangement and, seen in longitudinal extension of the respective stator module, at least at one end, a displacement sensor. Each stator module is disposed along a travel path of the respective rotor in an area of the respective stator module. Each displacement sensor has a detection range, within which it can detect a rotor, as long as the latter is located at least partially in the detection range. Each coil arrangement has an interaction range, within which, in case of energizing, the coil arrangement comes into interaction with the rotor and urges the latter in a driving direction, as long as the rotor is located with at least one portion in the interaction range. The at least two stator modules and the at least one rotor are disposed such that, at all times, a portion of the at least one rotor is located at least in the detection range of a displacement sensor and another portion of this rotor at least in the interaction range of a coil arrangement of the at least two stator modules. |
