Abstract:
1. A method of manufacturing a rotor comprising: stacking a plurality of sheets positioned parallel to a longitudinal axis extending through the rotor, the plurality of sheets defining a plurality of spaces therebetween to form a core having the plurality of spaces therein, wherein each of the sheets extend radially and parallel to the longitudinal axis; connecting a first end plate to an end of the core, the first end plate including a first hub connected to a first ring by a plurality of first spokes; connecting a second end plate to the first end plate, the second end plate including a second hub connected to a second ring by a plurality of second spokes; forming a substrate from the end plates and the core; staggering the plurality of second spokes from the plurality of first spokes to form pockets being defined between the plurality of first and second spokes; and casting a conductor to the substrate with the conductor flowing into the plurality of spaces of the core and the pockets to form a cast rotor.
