Abstract
A device includes a first rotor segment and a second rotor segment, wherein the first rotor segment and the second rotor segment are configured to be directly coupled together about a shaft to form at least a portion of a unitary rotor. The device also includes a first stator segment and a second stator segment, wherein the first stator segment and the second stator segment are configured to be directly coupled together to form at least a portion of a unitary stator.
Claims18
A device, comprising:
- a first rotor segment as at least a portion of a unitary rotor;
- a first stator segment;
- a second stator segment, wherein the first stator segment and the second stator segment are configured to be directly coupled together circumferentially about a shaft, wherein the first stator segment and second stator segment when directly coupled together form at least a portion of a unitary stator circumferentially disposed about the shaft, wherein the unitary rotor is disposed about the unitary stator as part of a reluctance motor;
- a first housing segment;
- and
- a second housing segment, wherein the first housing segment and the second housing segment are configured to be directly coupled together circumferentially about the unitary stator, wherein the first housing segment and second housing segment when directly coupled together form at least a portion of a housing circumferentially disposed about the unitary stator.
