| 20110025141 | STATOR COMPACTED IN ONE PIECE - A compaction tool is provided for compacting an element from metal powder where the element has uniform axially displaced protrusions, and the tool comprises a die and a top and a bottom punch with punch surfaces. The top and bottom punch comprises displaceable opposing punch surfaces for displacing the metal powder there between before compacting the element. Additionally provided are a method for compacting an element from metal powder and an element made from such a method. | 02-03-2011 |
| 20110037329 | INTEGRATED ROTOR POLE PIECES - A pole piece structure is provided to be used as part of an active rotor structure for an electrical rotary machine, wherein the active rotor structure is circular comprising pole pieces and permanent magnets magnetised in the circumferential direction of the rotor structure, wherein the rotor pole piece structure is a single structure with at least two individually spaced pole pieces connected by an integration bridge. Further provided is a method of manufacturing a rotor pole piece structure and a rotor for an electrical machine with a rotor pole piece structure. The assembly of magnets to the pole pieces is significantly enhanced using these rotor pole piece structures as described. | 02-17-2011 |
