Patent ID: 7378763

Claim:
Stator core for a linear motor, said stator core 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, wherein the first tooth and the second tooth are arranged in close contact with each other and wherein the extension of the teeth is small in the radial direction in the area of the contact between the two teeth in order to reach magnetic saturation in this portion of the stator during operation.
