HIGH EFFICIENCY TRANSVERSE FLUX MOTOR FAN |
摘要 |
<p>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 staler 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, (SOOCFM/watt), an essential airflow density of more than about 2.36 L/s*g, (5 CFy/gram) and a power density of about 150W/kg or more.</p> |
