Using vibration analysis to evaluate machine health has many benefits, and with advances in sensor, recording, and analysis technology, vibration analysis is now within the reach of even small organizations.
DC motors possess linear relationships that allow for very predictable operation. For instance, if enough voltage is applied across the terminals of a DC motor, the output shaft will spin at a rate proportional to that applied voltage. You can take the ratio of the applied voltage over the rated voltage and multiply that number by the no load speed and get the running speed.
V-belts look like relatively benign and simple pieces of equipment. They're basically a glorified rubber band, right? Need a replacement? Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There's only one problem: that approach is about as wrong as you can get.
