Axial movement of large synch motor - Electric motors & generators engine…

25/4/2010· I have a large motor, horizontal, (syncroneous)driven by an LCI. After one or two hours at high speed the rotor starts to slowly move back and forth. If I lower the speed the oscilations increases up to aprox 1HZ. What would be the axial forces doing that. I do not think that the drive is at fault. After cooling down, all is allright, for 1-2 hrs.

Understand Vertical Motor Bearings - Efficient Plant

11/4/2018· Vertical motors are classified as normal thrust, in-line thrust, or high thrust. Normal thrust loads can be determined from tables based on the motor’s speed and horsepower rating. High thrust is a multiple of normal thrust, such as 175%, 250%, and 300%. We will see, later in this article, how bearings are arranged to accommodate each of

Electric Motor Bearing Greasing and Lubriion

Electric Motor Bearing Greasing and Lubriion. Rolling-element bearings used in electric motors are at risk for various modes of failure if an incorrect maintenance or lubriion strategy is implemented. These include incorrect lubricant selection, contamination, loss of lubricant and overgreasing. This article discusses several effective

HECO All Systems Go - The Importance of Electric Motor Bearings

These bearings don’t require a cage and race in the same way that ball bearings do. Electric motor roller bearings are used for belted appliions with motors 150 HP and above. The surface of the cylindrical shape rolling elements helps to account for the high level of radial load that the belts put onto the bearings.
