A newly filed patent (Publication Number: US20240038479A1) describes an innovative x-ray tube system designed with a unique stator assembly positioned within cooling oil to enhance performance. The system includes a housing containing cooling oil, a vacuum envelope with an anode and cathode, a rotor on liquid metal bearings, and a stator assembly with stator teeth and windings creating intra-slot cooling channels. The design ensures efficient cooling and immersion of stator teeth in the oil, improving overall system functionality.

Furthermore, the patent details various configurations and dimensions of the stator assembly, rotor, and motor controller settings to optimize the x-ray tube system's operation. With specific ratios of copper in stator windings, trapezoidal slot volumes, and precise distances between components, the system aims to achieve maximum efficiency and performance. Additionally, the motor controller allows for mode-specific control settings, including a ramp setting for starting rotation and a steady-state setting for imaging, showcasing a comprehensive approach to enhancing the x-ray tube system's capabilities.
