  • Linear motor
    Patent number: 7884508
    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.

  • Core back of an electrical machine and method for making the same
    Patent number: 7064469
    Abstract: An essentially ring shaped core back for an electrical machine comprising a plurality of stacked, ring shaped sheets of soft magnetic material, a barrier of electrical resistance arranged between two adjacent sheets of soft magnetic material for reducing effects of eddy currents. At least each sheet of soft magnetic material in a subset of said plurality of stacked, ring shaped sheets of soft magnetic material includes a plurality of circumferentially arranged tooth openings that are extending axially through each sheet in said subset of said plurality of stacked, ring shaped sheets of soft magnetic material, additionally, each sheet of said subset of said plurality of stacked, ring shaped sheets of soft magnetic material includes a first inner closing portion and a second inner closing portion that are arranged between each tooth opening and an inner perimeter of said ring shaped sheet of soft magnetic material.
