Abstract
A bell-shaped rotor of an electric machine includes a cylindrical segment and a conical segment, wherein the cylindrical segment has magnetically active regions and nonmagnetic regions, where the rotor is produced at least partially via an additive production method, where the electric machine includes, in particular, an outer stator, an inner stator, which is arranged concentric to the outer stator within the outer stator, and the rotor, which is arranged concentric to the outer stator and the inner stator between the outer stator and the inner stator.
Claims20
A rotor of an electric machine, rotor comprising:
- a cylindrical section having magnetically active areas and non-magnetic areas;
- and
- an additively manufactured conical section having a web structure arranged entirely within a periphery of the additively manufactured conical section.
An electric machine comprising:
- an external stator;
- an internal stator arranged concentric to the external stator and within the external stator;
- and
- a rotor comprising a cylindrical section having magnetically active areas and non-magnetic areas and an additively manufactured conical section having a web structure arranged entirely within a periphery of the additively manufactured conical section, the rotor being arranged concentric to the external stator and the internal stator between the external stator and the internal stator and which is moveable relative to the external stator and the internal stator;
- wherein the external stator includes a plurality of windings, the internal stator includes a plurality of permanent magnets;
- and
- wherein the rotor comprises a carrier element formed from a non-magnetic material and which has a plurality of cutouts into which a soft-magnetic segment is arranged in each case.
A method for producing a bell-shaped rotor of an electric machine, the method comprising:
- manufacturing the bell-shaped rotor at least partially via an additive manufacturing method;
- and
- manufacturing a lamination by alternately solidifying different materials.
