Abstract: A powder including a plurality of particulates, each particulate including a soft magnetic metallic core coated with a continuous dielectric coating having a thickness selected from a range of 100 nanometers to 100 micrometers. The particulates have a mean particle size selected from a range of 100 nanometers to 250 micrometers. Methods for forming the powder are disclosed. A soft magnetic composite component includes a soft magnetic material in a dielectric matrix, wherein (i) the soft magnetic material comprises a plurality of particulates comprising metallic cores, (ii) each metallic core is coated by a continuous dielectric coating covering >90% of a surface area of the metallic core, (iii) the metallic cores are electrically isolated from each other, and (iv) the dielectric coatings of adjacent metallic cores are consolidated together. Methods for formation of the soft magnetic component by additive manufacturing and hot isostatic pressing are disclosed.

Abstract: An induction heating system and method includes a work piece that may be a multi-layer pipe. The multi-layer pipe includes an inner layer for conveying effluent and an outer layer surrounding at least a portion of the inner layer. The outer layer has a higher Curie temperature than the inner layer such that the outer layer remains magnetic at or above a reaction temperature of the effluent to maximize hysteresis losses in the pipe up to and beyond the reaction temperature of the effluent. The inner layer may have desirable mechanical, thermal, and chemical properties such that the combination of the outer layer and the inner layer results in a multi-layer pipe that is efficient for induction heating up to and beyond the reaction temperature, while also being mechanically and thermally suitable for hydrocarbon processing applications.

Abstract: Systems and methods are disclosed for manipulating the noise and vibration of a switched reluctance machine (SRM). By use of vibration sensors and real-time optimization methods, the noise and vibration profile of an SRM and associated load may be modified to meet one or more control objectives, such as torque ripple mitigation (TRM), harmonic spectrum shaping, and/or efficiency improvement.

Abstract: Systems and methods to manipulate the noise and vibration of a switched reluctance machine (SRM), capable of being implemented in a controller. By use of vibration sensors and a real-time optimizer, the noise and vibration profile of an SRM and associated load can be modified in order to meet multiple control objectives, such as torque ripple mitigation (TRM), harmonic spectrum shaping, and efficiency improvement. The systems and methods can be adapted to high power, high pole count, and high speed applications, and applications where electrical or mechanical imbalance exists.
