摘要： An arrangement to ensure an air gap in an electrical machine is provided. The electrical machine has a stator arrangement and a rotor arrangement, the rotor arrangement rotating around a longitudinal axis. An air gap is defined by a distance between parts of the rotor arrangement and parts of the stator arrangement, wherein the parts of the stator arrangement are opposite to the parts of the rotor arrangement along a certain length. The stator arrangement includes a lamination stack which is constructed to support a winding of a stator-coil, and the rotor arrangement includes a plurality of permanent magnets. A cross section of the air gap changes along the certain length such that the air gap is not uniform in view to the certain length. The cross section of the air gap is configured by a change in a shape of the lamination stack along the certain length.

摘要： Various embodiments relate generally to electrodynamic machines and the like, and more particularly, to rotor assemblies and rotor-stator structures for electrodynamic machines, including, but not limited to, outer rotor assemblies and/or inner rotor assemblies. In some embodiments, a rotor-stator structure includes a rotor structure in which rotor assemblies are arranged on an axis of rotation. A rotor assembly can include an arrangement of magnetic regions each having a portion of a surface that is oriented substantially at an angle to the axis and disposed externally to, for example, a portion of a conically-shaped space centered on the axis of rotation. The rotor-stator structure also can include pole members (e.g., field pole members) having pole faces. A subset of the pole faces can be positioned to confront the arrangement of the magnetic regions to establish air gaps, with the subset of the pole faces being disposed internally to the conically-shaped space.

摘要： An electromagnetic machine stator has a common pole and a plurality of excitation poles. Each excitation pole has a coil wound around it for inducing a magnetic flux through the excitation pole. The common pole that does not have a coil wound around it for inducing a magnetic flux. A flux barrier, disposed within the common pole, inhibits the flow of flux from one part of the common pole across the flux barrier to another part of the common pole. The flux barrier is less conducive to the flow of flux than is the common pole.
