An end plate for a rotor of a switched reluctance motor is disclosed. The end plate includes an annular body and a plurality of ribs. The annular body has a first axial end, a second axial end, and a thickness. Further, the annular body defines an outer surface and a bore configured to receive a shaft of the rotor. The plurality of ribs extends radially outwardly from the outer surface. The plurality of ribs is adapted to respectively abut with a plurality of poles of the rotor.

A fault detection system for a machine having a plurality of electrical conducting elements insulated from a frame ground of the machine is disclosed. The fault detection system may include a high voltage DC power source, a positive high voltage bus connected to a positive terminal of the high voltage DC power source and providing high voltage electrical power to the plurality of electrical conducting elements, and a negative high voltage bus connected to a negative terminal of the high voltage DC power source and returning high voltage electrical power from the plurality of electrical conducting elements. At least one of the positive and negative high voltage buses may be selectively connected through a plurality of switches to plural zones of the electrical conducting elements, with each of the plural zones being electrically connected in parallel, and selectively connected to the high voltage DC power source by one of the plurality of switches. A low voltage DC power source may be configured to form part of a leakage current detector selectively connected through each of the plurality of switches to each of the plural zones for detecting leakage current between an electrical conducting element and the frame ground.

A debris guard includes a plurality of fasteners and an outer cover including two or more sections that when assembled form an annular inner wall. Each of the two or more sections includes at least one mounting feature shaped to receive at least one of the plurality of fasteners. An inner guard includes a mounting portion and a seal.
