A stator is disclosed. The stator has a stator core that has stator poles protruding in a radial direction and a stator. The stator core has an axial groove formed on its outer surface along a longitudinal axis that is used to direct a cooling fluid from a first end of the stator core towards a second end of the stator core that is opposite the first end. Further, the stator core has an annulus groove formed on its outer surface, with the annulus groove in fluid communication with the axial groove. The annulus groove receives the cooling fluid from the axial groove, and is located between the first end and the second end of the stator core.

A modular inverter arrangement comprising one or more cages of a cage assembly, including at least a first cage of the cage assembly. Each of the one or more cages can be in the form of a cuboid, and each of the one or more cages can be adapted to accommodate therein respective sets of one or more power modules. The modular inverter arrangement can also be comprised of a heatsink extending transversely through each of the one or more cages, from a first end of the cage assembly to a second end of the cage assembly opposite the first end.

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.
