    Abstract: A system includes a magnetic material supply for regulating a magnetic material flow rate of a magnetic material and a binder material supply for regulating a binder material flow rate of a binder material. A nozzle is configured for depositing a deposition mixture of the magnetic material and the binder material on a surface and a preheater is configured to preheat the deposition mixture before depositing on the surface. A controller is in operative communication with the magnetic material supply, the binder material supply, and the preheater. The controller is configured to receive an inductor core design file that represents a geometry and a magnetic permeability distribution of an inductor core, move the nozzle to one or more deposition locations, and adjust the magnetic material flow rate to the binder material flow rate to achieve a deposition mixture having a desired magnetic permeability at the deposition locations.

    Abstract: Systems and methods are disclosed for on-line monitoring of the condition of the stator insulation of an AC motor or an electric generator. In certain embodiments, the system includes a transformer surrounding each pair of input and output cables associated with a given phase of power provided to the AC motor or generated by the electric generator. In another embodiment, a transformer surrounds the three input cables (for an AC motor) or the three output cables (for an electric generator) that correspond to phases of the AC motor or electric generator. In both embodiments, the transformers generate voltages that may be used to monitor leakage currents associated with the cables. A microcontroller monitors the voltages generated by the transformers and determines the condition of the stator insulation of the AC motor or the electric generator based on the voltages.
