Abstract (en)

[origin: WO2005066982A1] An electromagnetic linear drive comprises a stator (2) and an armature (7). A relative movement between the stator (2) and the armature (7) can be effected. An air gap (9, 9a, 9b) is formed between a surface of the armature (7) and of the stator (2) at least during a relative movement. The air gap (9, 9a, 9b) is slanted with regard to the direction of the relative movement.
