Abstract: An axial flux electric machine comprises a rotor assembly configured to rotate about an axis of rotation. A stator core is coupled to the rotor assembly. The stator core comprises a stator core base and a plurality of circumferentially-spaced stator teeth extending from the base in a direction parallel to the axis. Each stator tooth of the plurality of stator teeth comprises a top surface, a pair of opposing circumferential sides, and a chamfered portion defined at an intersection of the top surface and each of the pair of opposing sides. The chamfered portion facilitates reducing an amount of torque ripple produced by the axial flux electric motor.

Abstract: A water heater system comprises a water tank, a burner plenum, a flue, a blower, a combustion air passageway, a dilution air passageway, an upstream manifold, and a downstream manifold. The upstream manifold divides air from the blower so that some air flows through the combustion air passageway to the burner plenum and some air flows through the dilution air passageway to the downstream manifold. The downstream manifold combines the air from the dilution air passageway with combustion products from the flue.

Abstract: A two-phase switched reluctance machine is provided using discontinuous core structures as the stator for low-cost, high-performance drives. This discontinuous stator core structure contains short flux paths and maximum overlap between the rotor poles and stator poles in the stator discontinuous core structures, regardless of the rotor position. Example configurations of such core structure include E-core, L-core and I-core configurations. Using less steel and magnet wire than in conventional SRM designs results in cost savings of stator material and winding material. Efficiency of this novel SRM is improved because of shorter flux paths resulting in reduction of core losses and decreased phase resistance resulting in reduction of copper losses. Two-phase simultaneous excitation of the novel SRM can reduce torque ripple during commutation as compared with existing two-phase SRMs.

Abstract translation: 使用不连续的核心结构作为用于低成本，高性能的驱动器的定子来提供两相开关磁阻电机。 这种不连续的定子铁芯结构在定子不连续的铁芯结构中包含短的磁通路径和转子磁极和定子极之间的最大重叠，而与转子位置无关。 这种核心结构的示例配置包括E核，L核和I核配置。 使用比常规SRM设计更少的钢和电线导致定子材料和绕组材料的成本节约。 这种新型SRM的效率得到改善，因为较短的磁通路径导致磁芯损耗的减小和相位阻力的降低，导致铜损耗的减少。 与现有的两相SRM相比，新型SRM的两相同步励磁可以减少转换期间的转矩波动。
