1. A load apparatus comprising:
- a load configured to convert mechanical rotational energy to electrical energy for a power output;
a rotor assembly coupled to said load, wherein said rotor assembly comprises a rotor shaft that is configured to rotate within at least a portion of said load; and
a quill shaft comprising a first end portion coupled to said rotor shaft and a second end portion comprising an interior portion and an exterior portion that substantially circumscribes at least a portion of said interior portion, said second end portion is configured to couple to a drive shaft of a machine such that said quill shaft is enabled to couple said rotor shaft to the drive shaft such that said rotor shaft is at least one of axially and radially isolated from the drive shaft to facilitate rotordynamic isolation between said load apparatus and the machine.

Abstract
A load apparatus is provided. The load apparatus generally comprises a load that is configured to convert mechanical rotational energy to electrical energy for a power output. A rotor assembly is coupled to the load, wherein the rotor assembly includes a rotor shaft that is configured to rotate within at least a portion of the load. A quill shaft is coupled to the rotor shaft, wherein the quill shaft is configured to couple the rotor shaft to a drive shaft of a machine such that the rotor shaft is axially and/or radially isolated from the drive shaft to facilitate rotordynamic isolation between the load apparatus and the machine.
