Abstract:
A linear motor comprising a stator core and/or a mover. The stator core of said linear motor comprising an inner perimeter, an outer perimeter essentially encircling the inner perimeter, a first and a second tooth being arranged along one of the inner perimeter or the outer perimeter, a slot for receiving a stator coil, said slot being a cavity arranged within the stator core, wherein said stator core is divided into a first stator part and a second stator part, said first stator part including the first tooth, being arranged to partially define the slot, and being made of soft magnetic powder, and said second stator part including the second tooth, being arranged to partially define the slot, and being made of soft magnetic powder. The mover of said linear motor comprising at least one section of soft magnetic material and at least one permanent magnet, the at least one section of soft magnetic material and the at least one permanent magnet being aligned in an axial direction of the mover, wherein a polarization vector of said at least one permanent magnet is directed axially.
