Baldor Electric Company Introduces New Line of Motors: Super-E® Motors with Baldor Shaft Grounding Brush
Press release date: May 15, 2014
While the use of across-the-line motors is still common in industry today, the use of drives to control motors has become more prevalent in recent applications. Using a drive to control the motor is beneficial because it provides speed control on different applications such as fans, pumps and conveyors, allowing users to run their motors at optimum efficiency. However, when motors are controlled by a drive, it can create the potential for common mode voltage, which can cause voltage spikes in the rotor. These spikes seek the path of least resistance – the motor bearings -- and can lead to premature bearing failure. The internally mounted Baldor Shaft Grounding Brush can prevent the voltage spikes from damaging the bearings.
