A work vehicle and energy storage device include an electric machine having a stator and a rotor. The rotor is configured to rotate from the flow of electrical current provided to the electric machine, rotate to store energy of the work vehicle, provide a rotor mass to an end of the work vehicle, and generate electrical current for the work vehicle from rotation of the rotor. The rotor mass is greater than a stator mass.

Work vehicle and energy storage device having an electric machine and a rotor mass

A work vehicle and energy storage device include a ballast providing ballast weight to the horizontal end of the work vehicle, a stator of an electric machine having a vertically extending axis, and a rotor of the electric machine fixed for rotation with the ballast.

Work vehicle having electric machine and energy storage device

An energy storage device for storing energy generated from operation of a work vehicle includes a ballast providing ballast weight to the work vehicle, a stator of an electric machine mounted on the work vehicle, a rotor of the electric machine fixed for rotation with the ballast, spaced from the stator by a gap, and configured for rotation relative to the stator such that the electric machine is configured to generate electrical current from rotation of the rotor and the ballast relative to the stator and to rotate the rotor and the ballast from electrical current received by the electric machine, and a gap modulator coupled to at least one of the stator and the rotor and configured to selectively adjust the gap between the rotor and the stator based on an operation of the electric machine.

Method of electric machine gap adjustment, work vehicle, and energy storage device

A work vehicle and energy storage device include a ballast providing ballast weight to the horizontal end of the work vehicle, a stator of an electric machine having a vertically extending axis, a rotor of the electric machine fixed for rotation with the ballast and configured for rotation about the vertically extending axis, and a bearing supporting the ballast weight and the rotor for rotation of the rotor relative to the stator.
