    摘要： Electrical machine arrangements have advantages with regard to providing local electrical power and starting. Embedding such electrical machine arrangements in machinery such as gas turbine engines is advantageous in removing mechanical linkages and reducing aerodynamic drag. However, the components utilized must be able to withstand harsh environmental conditions and therefore the DC link capacitor used for smoothing of voltage fluctuations are limited to relatively low capacitance densities. Low density DC link capacitors require large sizes which render electrical machines less acceptable for embedded usage. By providing offset of electrical current in inductance elements such as stator windings and stator coils of electrical machines in dead periods of the cycle a reduction in DC link capacitor requirements is achieved reducing the size, weight and complexity of installing electrical machines in gas turbine engines.

    摘要翻译： 电机装置在提供局部电力和启动方面具有优势。 在诸如燃气涡轮发动机的机械中嵌入这样的电机装置有利于去除机械连杆并减小空气动力学阻力。 然而，所使用的部件必须能够承受恶劣的环境条件，因此用于平滑电压波动的DC链路电容器被限制在相对低的电容密度。 低密度直流链路电容器需要较大的尺寸，这使得电机不适合嵌入式使用。 通过在循环的死区中提供诸如电机的定子绕组和定子线圈的电感元件中的电流偏移，可以减少DC链路电容器的要求，从而降低了在燃气涡轮发动机中安装电机的尺寸，重量和复杂性。

    摘要： A flux-switching machine stator comprising two or more C-cores, each C-core having two legs and a back portion joining the legs, and a permanent magnet arranged between legs of adjacent C-cores. Each leg has a main portion and a tip portion further from the back portion characterized in that the tip portion of each leg is angled relative to the main portion of the respective leg.
