Abstract
Electrical machines as provided herein can include a shaftless rotor with an annular array of permanent magnets; and a stator with an annular ferromagnetic core and a plurality of electromagnetic inductors about the ferromagnetic core. The stator is located adjacent to and substantially co-axial with the shaftless rotor; and a fluid thrust bearing located in an axially planar gap between the stator and the shaftless rotor.
Claims18
An electrical machine, comprising:
- a shaftless rotor comprising an annular array of permanent magnets;
- a stator comprising an annular ferromagnetic core and a plurality of electromagnetic inductors about the ferromagnetic core, the stator being located adjacent to and substantially co-axial with the shaftless rotor;
- and
- a fluid thrust bearing located in an axially planar gap between the stator and the shaftless rotor;
- wherein the annular array of the permanent magnets of the shaftless rotor and the annular ferromagnetic core and electromagnetic inductors of the stator have a magnetic attraction that provides a co-axially centering force on the shaftless rotor.
2 more elements
A stator, comprising:
- a plurality of modules, each module comprising:
- a ferromagnetic core;
- a plurality of electromagnetic inductors;
- and
- a module mount enclosing at least an outer portion of the ferromagnetic core and the electromagnetic inductors;
- and
- a retainer that is attached to a portion of the module mount of each module, the retainer linking the plurality of modules into a radially annular shape.
