FORT SMITH, AR—The Baldor Electric Company has announced the debut of its new line of electric motors – Super-E motors with Baldor Shaft Grounding Brush. See image above showing the cut-away of the Super-E motor.
Stock ratings available include one through 50 HP in Totally Enclosed Fan Cooled (TEFC) or Open Drip Proof (ODP) Foot Mounted designs along with 1/2 through five HP in TEFC, C-Face Foot Mounted designs.
The new Super-E Motor with Baldor Shaft Grounding Brush is designed with a carbon brush mounted internally to divert shaft currents away from motor bearings, thus increasing the life of the bearings.
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.
Baldor Electric Company is a leading marketer, designer and manufacturer of industrial electric motors, drives, and mechanical power transmission products. Baldor, a member of the ABB group, is headquartered in Fort Smith, Arkansas. For company and product information, visit www.baldor.com.
