The fixed part is a cylindrical tube (12) with coils (16a,16b,17a,17b,18a,18b) on its inside for producing a travelling magnetic field that drives a movable armature (20) within the tube. The armature has at least one permanent magnet whose North and South poles face alternately inwards and outwards.
