Abstract: Unique systems, methods, techniques and apparatuses of a modular power transformer are disclosed. One exemplary embodiment is a matrix power transformer including a plurality of block assemblies each including a plurality of transformer modules, each transformer module including a primary winding coupled to an input and a secondary winding coupled to an output, the inputs of each transformer module in one block assembly being coupled together and the outputs of each transformer block being coupled together. One of the secondary windings includes a plurality of taps structured to be selectively coupled to the output of the associated transformer module assembly or another secondary winding of the associated module assembly.

Abstract: A method for manufacturing for an electrical machine includes: stacking a plurality of rotor laminations to form an axial rotor segment, the rotor segment formed of at least two laminations, each lamination having a plurality of openings therein, the openings forming a plurality of rotor poles in the rotor segment, each pole having a plurality of passages formed from the openings; rotating the rotor segment to place a first pole of the plurality of poles in an alignment position; injecting into the passages of the first pole a polymer bonded permanent magnet (PBM) material in molten form, wherein the (PBM) material includes magnetic particles suspended within a polymeric matrix; subjecting the first pole to a desired magnetic field to align the magnetic particles into a desired orientation prior to solidification of the (PBM) material; and solidifying the (PBM) material to form permanent magnets within the passages of the first pole.

Abstract: Unique systems, methods, techniques and apparatuses of a power transformer are disclosed. One exemplary embodiment is a transformer comprising a core; a first winding wound around the core; a second winding coaxially wound around the first winding so as to surround the first winding and forming an air gap between the first winding and second winding; and a plate having a relative permeability greater than 1 and less than 25 structured to be inserted into the air gap.

Abstract: Auto balancing transformers are disclosed for balancing a multi-phase electrical system by varying the degree of electromagnetic coupling between primary and secondary winding. The auto-balancing transformer includes a movable to selectively couple primary phases with two or fewer phases of the secondary system.
