Two-pole motors can be more challenging to repair because of the vibration issues that can be related to the units operating at higher speeds, which means there are special tests that need to be performed on them. Without checking characteristics such as runout and roundness, there is a chance that vibration won’t show up until …

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 …

Bearings account for about 51% of all electric motor failures and the most common sources of failure involve normal wear and tear, lubrication issues, contamination, or electrical damage that affects the bearing surfaces. While rolling element bearings are the most common type of bearing, sleeve bearings are found most often in larger motors that require a …

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 …
