<i>Predictive maintenance cuts economic and safety risks in rotating machinery by leveraging vibration and acoustic data, which machine-learning |
|
|
models convert into intelligent fault detectors. Acoustic signals are especially powerful for early fault detection and cooling fans, with simple rotational dynamics, |
|
|
are convenient proxies for complex rotors. Yet existing fan datasets lack disturbance models and controlled conditions. We present CANDAS, a controlled sound dataset |
|
|
featuring 28 h of recordings from two cooling fans under five modeled disturbance conditions. |

- ## Setup |
|
|
<h5>The experimental setup was carefully designed to collect sounds from cooling fans under different weight configurations and voltage levels. To compose our experimental setup, |
|
|
we selected two models of cooling fans: the <i>Delta AUC0912D</i>, referred to as <b>A2</b>, and the <i>Intel AUC0912D</i>, referred to as <b>A3</b>—both commonly found in electronic devices. In order |
|
|
to obtain a greater variety of sounds, an experimental arrangement was defined in which five weight configurations were applied to each cooling fan, under <b>two voltage levels: 9 |
|
|
Volts and 12 Volts</b>. |

<h4>The black dots represent first-layer magnets attached to the cooling fan blades, while the blue dots indicate additional magnets stacked on top. It is possible to design both |
|
|
balanced configurations (i.e., Config 1) and severely unbalanced ones(i.e., Config 5).</h4> |
