If you have a specific NEMA-T frame motor, you can be assured that, regardless of the manufacturer, that specific T frame (for example, a 324T) will have the same shaft length, shaft diameter, and bolt hole mounting dimensions. However, what many people don’t realize is that the physical size of specific T frame motors can …

Just because your rotating equipment has started vibrating doesn’t automatically mean it needs to be balanced. There are several other issues that may be at work, and a thorough vibration analysis can reveal the true source of the problem. The 80-20 Rule for Balance Issues Your fan is vibrating and the natural assumption you make …

Industrial vibration analysis is a measurement tool used to identify, predict, and prevent failures in rotating machinery. When analyzing machine frequency vibrations, (frequency analysis) it is normal to find a number of important frequencies that are directly related to the movement of various parts of the machine. Vibration may influence the durability and reliability of …
