Abstract

Apparatus and associated methods relate to apparatus for balancing a fan. In an illustrative example, a fan balancing system may include a local device and a remote device. For example, the local device may include a sensing unit and a processing unit. The remote device may, for example, include a user interface and a controller wirelessly coupled to the local device. For example, the controller may receive a user input including a total number of blades of a fan from the user interface. When the fan is activated, a condensed imbalance profile may be received wirelessly from the local device releasably coupled to the fan. In some implementations, the controller may generate a balancing matrix including combinations of weights and positions of the weights along one or more blades of the fan. Various embodiments may advantageously generate a placement combination of weights to re-balance the fan remotely.

Dependent claims

A fan balancing system comprising:

a local device comprising a sensing unit and a processing unit, wherein the processing unit is configured to generate a condensed imbalance profile as a function of measurements detected by the sensing unit;
and,
a remote device comprising a user interface and a controller, wherein the controller is wirelessly coupled to the local device, and the user interface, wherein the controller comprises:
a data store comprising a program of instructions;
and,
a processor operably coupled to the data store such that, when the processor executes the program of instructions, the processor causes operations to be performed to remotely generate a placement combination of predefined balancing weights to be installed to rebalance a fan, the operations comprising:
receive, from the user interface, a user input corresponding to physical properties of a rotating fan, wherein the physical properties comprise at least a total number of blades of the rotating fan, such that angular locations of the blades on a rotating plane of the rotating fan are determined by evening distributing the total number of blades among 360° of the rotating plane;
receive the condensed imbalance profile from the local device, wherein the local device is releasably coupled to the rotating fan;
generate a balancing matrix comprising a weight and a position of the weight along a longitudinal axis of at least one of blades on the rotating fan;
and,
generate a balancing guidance to be displayed at the user interface based on the balancing matrix.
