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 including armature teeth embedding at least one permanent magnet, which armature teeth are spaced apart by slots for receiving an armature winding, and which armature teeth have an extended width portion towards the air gap. The extended width portion of the armature teeth begins in the longitudinal direction of the armature teeth already at the level of the armature windings.

A linear flux switching permanent magnet (FSPM) motor comprising:
- a longitudinal linear stator with stator teeth facing an air gap;
- and
- a mover comprising at least one armature comprising armature teeth embedding at least one permanent magnet, which armature teeth are spaced apart by slots for receiving an armature winding, and which at teeth have an extended width portion towards the air gap,
- wherein the extended width portion of the armature teeth begins in the longitudinal direction of the armature teeth already at the level of the armature windings,
- wherein the armature has at least one armature base from which armature members project in the direction of the air gap, which armature members form a part of the armature teeth, and
- wherein a tooth width increase of the armature teeth towards the air gap is formed of the width increased portions of two armature members embedding the permanent magnets as well as from the width increase of the first permanent magnet relative to the second permanent magnet.
