Abstract
A shaftless rotor assembly comprising first end cap, a second end cap, and a plurality of lamination stacks positioned between the first end cap and the second end cap. The shaftless rotor assembly further comprises a plurality of fasteners extending in an axial direction through the first end cap, through the plurality of lamination stacks, and through at least a portion of the second end cap, where the plurality of lamination stacks defines a hollow rotor core.
Claims18
A shaftless rotor assembly, comprising:
- a first end cap;
- a second end cap;
- a plurality of lamination stacks positioned between the first end cap and the second end cap that define a hollow rotor core;
- and
- a plurality of fasteners extending in an axial direction through the first end cap, through the plurality of lamination stacks, and through at least a portion of the second end cap, and wherein the plurality of fasteners is engagingly coupled via threading directly to a plurality of holes within the first end cap.

A shaftless rotor assembly comprising:
- a pair of end caps, where each end cap has a chamfered cylindrical flange extending axially inwards towards a rotor core of the shaftless rotor assembly;
- a plurality of lamination stacks having at least one keyway cutout for alignment with the pair of end caps;
- and
- a plurality of fasteners threaded through the pair of end caps and the plurality of lamination stacks parallel to an axis of rotation, and wherein the plurality of fasteners is inserted and threaded into a plurality of first holes formed through the plurality of lamination stacks directly within one of the pair of endcaps, a plurality of second holes formed in a first end cap, and a plurality of third holes formed in a second end cap, and wherein the plurality of fasteners is directly coupled to the plurality of first holes via threading.

A vehicle, comprising:
- a shaftless rotor assembly, comprising:
- a first end cap;
- a second end cap;
- a rotor core comprising a plurality of lamination stacks that is axially positioned between the first end cap and the second end cap, wherein a shaft does not extend through the rotor core, wherein the first end cap comprises a first flange that is in face sharing contact with an internally facing surface of a first end lamination stack of the plurality of lamination stacks;
- and
- a plurality of fasteners, wherein each of the plurality of fasteners extends through the first end cap, a material the plurality of lamination stacks, and the second end cap, and wherein the plurality of fasteners is positioned circumferentially around and radially spaced away from an axis of rotation of the shaftless rotor assembly, and wherein the plurality of fasteners is engagingly coupled via threading to a plurality of holes of the first end cap, wherein a central axis of rotation for the shaftless rotor assembly is aligned longitudinally in the vehicle;
- a transmission coupled to the shaftless rotor assembly, the transmission and the shaftless rotor assembly positioned in a front end of the vehicle;
- auxiliary devices;
- and
- a controller configured to operate the vehicle in power take-off, wherein the shaftless rotor assembly is used to deliver electrical energy to external, auxiliary devices during power take-off via the shaftless rotor assembly running during power take-off with drive wheels of the vehicle not in motion, allowing power output to be directed at least partially towards operating the auxiliary devices, the vehicle further including a power interface arranged along an electrical circuit of the vehicle, the power interface having a plurality of power outlets positioned in a rear of the vehicle, wherein each of the power outlets have a circuit breaker integrated therein.
