A linear flux switching permanent magnet (FSPM) motor includes a longitudinal linear stator with stator teeth facing an air gap and a mover including at least one armature including armature teeth, which are spaced apart by slots for receiving an armature winding. At least some, preferably all of the armature teeth embed at least two permanent magnets, respectively, which are positioned successively in longitudinal direction of the tooth, whereby the two permanent magnets have different magnetic properties.
