Abstract: An electrical machine includes a rotor with a rotational axis, a coil arranged circumferentially with respect to and fully encircling the rotational axis, and a stator assembly. The stator assembly includes first and second lamination stacks comprising associated pluralities of laminae, the stacks being arranged circumferentially with respect to the rotational axis on opposing sides of the coil for conducting magnetic flux. The stacks are configured with gaps generally radially through the laminae thereof, defining separate circumferential segments in each laminae, to prevent creating a continuous electrical circuit around the rotational axis in the segments. Each laminae has a connecting ring spaced radially from the segments, and beams connecting the segments to the ring as a unitary piece. Back return elements extend axially between the stacks to provide a flux path therebetween, and are positioned circumferentially between adjacent parts of the beams and radially between the segments and the ring.

Abstract: A high efficiency transverse flux motor fan utilizes a transverse flux motor that can provide torque to drive fan blades at a reduced weight over conventional induction and brushless DC motors. A fan incorporating a transverse flux motor may be a residential ceiling fan or high volume low speed fan. Transverse flux motors are ideal for these applications as they have a higher efficiency at low revolutions per minute. A transverse flux motor may have a stator utilizing a ring shaped lamina that has extending members that form a coil channel. A lamina may be a unitary piece of material that is formed from a sheet of metal, thereby providing a very lightweight stator assembly. An exemplary fan may provide an airflow efficiency of more than about 236 L/s*W, (500 CFM/watt), an essential airflow density of more than about 2.36 L/s*g, (5 CFM/gram) and a power density of about 150 W/kg or more.

Abstract translation: 高效率横向磁通电机风扇采用横向磁通电机，可以提供转矩，以比传统感应和无刷直流电机减轻重量来驱动风扇叶片。 结合横向磁通电机的风扇可以是住宅吊扇或高容量低速风扇。 横向磁通电机对于这些应用是理想的，因为它们在每分钟低转速下具有更高的效率。 横向磁通马达可以具有利用环形薄片的定子，该定子具有形成线圈通道的延伸部件。 层可以是由金属板形成的整体材料片，从而提供非常轻型的定子组件。 示例性的风扇可以提供大于约236L / s * W（500CFM /瓦特）的气流效率，大于约2.36L / s * g（5CFM / g）的基本气流密度和功率 密度约为150W / kg以上。
