A simple mathematical model can be used to estimate vibration at the top of the motor in a vertical pump-motor structure.
Why and how do leading OEMs choose a variable speed motor for their equipment?
Shaft failures do not happen everyday, but when they do, it can be a challenge to determine the cause of failure. Here's a technical explanation of what happens when the shaft bends or breaks.
The benefits of these motors provide the flexibility needed for challenging pump applications.
