Abstract: A stator-less electric motor for an MRI system is provided. The stator-less electric motor includes a body, a rotor rotatable connected to the body, and at least one coil winding disposed on the rotor. The at least one coil winding is arranged so as to rotate the rotor when energized via an electrical current in the presence of a magnetic field generated by a magnet assembly of the MRI system.

Abstract: An electronic filter assembly includes a magnetically conductive annular body extending around a center axis, a set of magnetically conductive prongs radially extending from the center axis toward the annular body, and conductive windings extending around the prongs. The conductive windings can be disposed around the prongs instead of the annular body to assist in conduction of common mode magnetic flux, to reduce impedance of the filter assembly, and/or to more evenly distribute temperature in the filter assembly. A method for forming an electronic filter assembly includes forming an electronic filter assembly having a magnetically conductive annular body extending around a center axis and a set of magnetically conductive prongs radially extending from the center axis toward the annular body. The annular body and the prongs can be formed by coupling plural layers of magnetically conductive bodies together.

Abstract translation: 电子滤波器组件包括围绕中心轴线延伸的导磁环形体，从中心轴线朝向环形体径向延伸的一组导电尖头以及围绕尖头延伸的导电绕组。 导电绕组可以围绕插脚而不是环形体设置，以辅助共模磁通的传导，以减小过滤器组件的阻抗，和/或更均匀地分配过滤组件中的温度。 一种形成电子滤波器组件的方法包括形成一个电子滤波器组件，该电子滤波器组件具有围绕中心轴线延伸的导磁环形体和一组从中心轴线向环形体径向延伸的导电尖头。 环形体和尖头可以通过将多层导磁体结合在一起而形成。
