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。
