Abstract: A magnetic power unit configured to couple to a rotating component and convert a rotation of the rotating component into energy. The magnetic power unit includes a rotor coupled to the rotating component such that the rotor rotates with a motion of the rotating component. The magnetic power unit further includes a stator and an asymmetric counterweight, disposed adjacent to the rotor such that the rotor surrounds the stator, coupled to the rotating component. The asymmetric counterweight may be configured to offset an effect of the rotation of the rotating component on the stator such that the stator maintains rotational staticity. The rotor may pass the stator with each rotation of the rotating component such that the energy is generated.

Abstract: A comprehensive system designed for the predictive maintenance of railcar wheel bearings, integrating multiple sensor modalities. The system includes thermography for temperature mapping, vibration analysis via a three-axis accelerometer, rotational velocity measurement using a rate gyro, and optical spectrometry for lubricant analysis. Each modality contributes to a holistic understanding of bearing health, enhancing maintenance strategies, safety, and operational efficiency in rail transportation.
