  • Variable Frequency Drives: Reducing Costs and Energy Use

    As mentioned before, here and here, VFDs are an excellent means to saving money and extending the life of your motor.  Amanda Griffith breaks out the benefits of variable frequency drives. For example: Variable-frequency drives are the most effective energy savers in pump and fan application. In most facilities, centrifugal pumps and fans run at one speed, with an automatic value, or some mechanical means, varying fluid flow rates. With a variable frequency drive, users can change motor speeds electronically. By adjusting a pump or fan speed to meet only the desired rate needed, one can signi

  • Vertical Hollowshaft Motors

    Wisconsin is the among the largest cranberry producer in the United States. L&S Electric helps serve their production by selling, and repairing, vertical hollowshaft motors. [caption id="attachment_233" align="alignright" width="156" caption="Hollowshaft Vertical Motor"][/caption] The history of the hollowshaft motor goes back almost 80 years: Introduced in 1922, vertical hollow shaft motors were developed to meet the specific needs of the vertical turbine pump industry. It is believed that Sterling Pump Corporation was the first pump company to work with a motor company (U.S. Electric M

  • An Overview on Uninterruptible Power Supply

    L&S Electric, along with Access Inc, will be holding several lunch-n-learns in the Fox Valley and Central Wisconsin in the next few months on Uninterrupted Power Supplies (UPS). An Excerpt: An uninterruptible power supply or continuous power supply is a device which provides a continuous supply of electric power to all the connected equipment by supplying power from a separate source when utility power is not available. UPS differs from an auxiliary power supply as auxiliary power supply does not provide instant protection from a momentary power interruption. More..... If you're inte

  • The Baldor Super-E Motors

    Super-E® Motors with AEGIS™ Shaft Grounding Ring 1 to 50 HP, 143T thru 326T With adjustable speed drives becoming more common in the motor industry, people are looking for ways to minimize shaft currents possibly created by adjustable speed applications. One way to minimize these currents is to mount a shaft ground to the motor, requiring either a custom motor or a motor modified in the field. Baldor worked closely with Electro Static Technology in the production of the Super-E Motors with AEGIS Shaft Grounding Ring. The grounding ring is uniquely installed internally on the motor. While m

  • Shaft Voltage Discharge Testing Provided by L&S Electric

    Bearing damage resulting from shaft currents going to ground through the bearing have become more and more common with in increasing use of variable frequency drive applications in industry. The best measurements to identify problem causing shaft currents are taken with an oscilloscope.  While in operation a probe is placed on an exposed area of the motor shaft to gather the shaft voltage data for analysis. Both DC and AC motors controlled by a variable frequency drive can cause shaft currents.   These shaft currents when going to ground through the bearing can be destructive causing the

  • Bearing Analysis provided by L&S Electric

    Why a bearing failed can be identified many times by tell tale wear patterns on the bearing components. Reliability can be improved if corrective actions can be implemented from the findings of bearing analysis. To see what kind of analysis L&S Electric provides, please read this PDF of a sample Bearing Analysis Report. Motor’s sent in for repair which you want bearing analyzed: Should your company send a motor into the shop which had failed prematurely or has a history of reliability issues please tag it to have bearings analyzed.  Bearings then are saved for analysis and orientatio
