Abstract
Official abstract text for this publication.
The described embodiments relate generally to cooling fans and more specifically to a method for balancing an impeller assembly included in a cooling fan. In one embodiment, a balancing ring with an asymmetric shape can be included in an impeller assembly and rotated to correct an unbalance in the impeller assembly. In another embodiment, a balancing ring assembly can be provided including an inner balancing ring and an outer balancing ring. The size and shape of the inner balancing ring can be modified to better correct any unbalance in the impeller assembly.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for balancing an impeller assembly in a cooling fan, the method comprising: analyzing an impeller assembly, that includes (i) an impeller configured to rotate about an axis and (ii) a magnet that is disposed within a recess of a central hub of the impeller assembly, for an amount of unbalance in the impeller assembly and determine a quantity and position of weight that can be added to the impeller assembly to reduce the amount of unbalance; and c…
