Abstract: Electrically resistive devices, such as voltage dividers, and methods of making the same are disclosed. An illustrative voltage divider may include a substrate having an axis, an electrically resistive path applied to the substrate, and at least one terminal positioned around the substrate and in contact with the electrically resistive path. The electrically resistive path may include a primary resistor and a secondary resistor, with the primary resistor having a higher electrical resistance than the secondary resistor. An adjustable displacement of the at least one terminal along the axis of the substrate may allow adjustment of at least one electrical resistance associated with the at least one terminal. An adjustable tightness of the at least one terminal around the substrate may allow adjustment of the at least one electrical resistance associated with the at least one terminal.

Abstract: A multi-layered conductor comprising one or more conductor layers of an electrically conductive material and one or more shielding layers of a soft magnetic material. The shielding layer can be coated onto the conductor layer and has a lower conductivity and a higher magnetic permeability than the electrically conductive material of conductor layers. The shielding layer can, at least when alternating current (AC) flows through the multi-layered conductor at relatively high frequencies, provide a separate power path for at least a portion of the high frequency AC current, as well as absorb at least a portion of the high frequency noises associated with that separated high frequency AC current. Additionally, the shielding layer can be separated from the conductor layer at an output end of the multi-layered conductor so that output ends of the shielding layer and conductor layer can be electrically connected to different electrical devices or components.

Abstract: A rotor core mold assembly including a rotor stack and a distribution plate. The rotor stack has a top surface and at least one rotor pole defined by a plurality of rotor stack cavities. Each of the plurality of rotor stack cavities has an aspect ratio defined by a width of a respective rotor stack cavity and a longitudinal length of the rotor stack. The distribution plate has a top surface and a bottom surface removably locatable on the top surface of the rotor stack to thereby form a fluid seal. The distribution plate includes a flow channel positioned on the top surface of the distribution plate and extending through the distribution plate, an injection gate in fluid communication with the flow channel, and a plurality of secondary flow channels coupled between the injection gate and the bottom surface of the distribution plate in fluid communication with the injection gate.

Abstract: A method for forming an article of manufacture using additive manufacturing, includes: a processor executing program instructions to: (a) rotate an object continuously about a horizontal axis using a first rotational stage, wherein the object is partially submerged in a bath of energy curable liquid formulation during the rotation; (b) control a rate of rotation of the object to achieve a desired radial thickness of a sub layer of uncured liquid formulation at a desired rotational location on the object; (c) direct an energy source to provide an energy dose onto the object at a desired rotational location, wherein the energy dose is configured to cure and solidify the sub layer; and repeat (a), (b) and (c) until a desired radial thickness of a cured liquid formulation layer is a achieved.

Abstract: A permanent magnet motor is provided that produces variable magnetic flux. The motor may include two different types of permanent magnets with different coercivities. The magnetic state of one of the magnets may be altered during use. In one state, the effective magnetic flux of the motor is greater, and in another state, the effective magnetic flux of the motor is less.
