Abstract
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 with armature teeth, whereby at least some of said, preferably all of said armature teeth embed at least one permanent magnet, respectively, which armature teeth are spaced apart by slots for receiving an armature winding. The permanent magnets embedded in the corresponding armature teeth protrude by an overhang over the back of the armature in a direction facing away from the air gap.
